I don't believe the outer position is updated when you set the y-label. Does this fix your problem?

figure;
a1=axes('outerposition',[0 0 .333 1]);
a2=axes('outerposition',[0.333 0 .333 1]);
a3=axes('outerposition',[.666 0 .333 1],'yaxislocation','right');
ylabel(a3,'axis3b');

It fixed it for me.

MATLAB: Changing YLabel position and outerposition

Source of the problem (scroll down for solution)

TL;DR: Changing the position of the y-axis label triggers an axis resize that doesn't account for rotated y-axis labels.

Here's a demo similar to yours that illustrates the problem.

1) Create an axes with a y-axis label in its default orientation. Draw a red rectangle around the OuterPosition of the axes and a green rectangle around the Position/InnerPosition of the axes.

figure('color', 'w', 'MenuBar', 'none'); 
ax1 = axes('OuterPosition',[.25 0.40 .7 0.50]);
ax1.ActivePositionProperty	= 'outerposition';
plot(ax1,0:10,0:10);
ax1.Title.String		= 'Preserve OuterPosition';
ax1.YLabel.String		= 'Preserve OuterPosition';
ah(1) = annotation('rectangle',ax1.OuterPosition,'Color', 'r','LineWidth',2);
ah(2) = annotation('rectangle',ax1.Position,'Color','g','LineWidth',2);

2) Rotate the y-axis label and set alignment. Draw blue dashed rectangles showing the updated position properties.

ax1.YLabel.Rotation		= 0;
ax1.YLabel.HorizontalAlignment	= 'right';
ax1.YLabel.VerticalAlignment	= 'top';
ah(3) = annotation('rectangle',ax1.OuterPosition, 'Color', 'b', 'LineStyle','--','LineWidth',2);
ah(4) = annotation('rectangle',ax1.Position, 'Color', 'b','lineStyle','--','LineWidth',2);

As you can see, the OuterPosition propery is preserved and the Position/InnerPosition properties have been adapted to the rotated y-axis label.

3) Change the vertical position of the y-axis label. Draw black dotted rectangles showing the updated position properties.

ax1.YLabel.Position(2)		= ax1.YLabel.Position(2)+2; % outerposition mode of axes don't work for YLabel after the line

ah(5) = annotation('rectangle',ax1.OuterPosition, 'Color', 'k', 'LineStyle',':','LineWidth',3);
ah(6) = annotation('rectangle',ax1.Position, 'Color', 'k','lineStyle',':','LineWidth',3);

As you can see, the original position property values have been returned as if the y-axis label were still oriented at 90 degrees.

Solution to the problem

Record the Position value of the axes prior to changing the y-axis label position. After changing the y-axis label position, reset the axes to its original position.

This is applied to the code from your demo.

figure; 
ax1				= axes('OuterPosition',[0 0.50 1.0 0.50]);
plot(ax1,0:10,0:10);
ax1.Title.String		= 'Preserve OuterPosition';
ax1.YLabel.String		= 'Preserve OuterPosition';
ax1.YLabel.Rotation		= 0;
ax1.YLabel.HorizontalAlignment	= 'right';
ax1.YLabel.VerticalAlignment	= 'top';
prePosition = ax1.Position; % RECORD THE POSITION OF THE AXES PRIOR TO LABEL POSITION CHANGE
ax1.YLabel.Position(2)		= ax1.YLabel.Position(2)+2; % outerposition mode of axes don't work for YLabel after the line
ax1.Position  = prePosition; % RESET THE AXIS POSITION

MATLAB: How to set an axis outside the polar figure

I've modified your code. Not sure how robust this solution is, but you can try this:

figure(2)
set(gcf,'color','w');
ax = polaraxes('Position', [0.25 0.25 0.6 0.6])
ax.ThetaDir = 'counterclockwise';
ax.ThetaZeroLocation = 'left';
rlim([70,120])
ax.RTickLabel = [];
ticks = [-flip(ax.RTick(2:end)) ax.RTick];
a = axes('Color', 'none',...
    'XColor', 'none',...
    'Position', [ax.Position(1),ax.Position(2)+ax.Position(4)/2,...
    ax.Position(3),ax.Position(4)/2],...
    'YLim', [ax.RLim(1) ax.RLim(2)],...
    'YTick', ticks,...
    'YTickLabel', abs(ticks));
a_m = copyobj(a,gcf)
a_m.Position = a.Position - [0 a.Position(4),0,0];
a_m.YAxis.Direction = 'reverse';
ylabel(a, 'r axis label')
a.YAxis.Label.Position = [a.YAxis.Label.Position(1),70,0];
