MATLAB: Does the “Enabled Subsystem” not work

Question

When trying out "Enabled Subsystem" I encounter a strange Problem: The block seems not to work. But strangely the same block copied from the "enablesub"-example seems to work (see Picture and attached Model). I have no idea why this is the case since i compared every Parameter of the two Subsystem-blocks and the enabled block.

I am using Matlab Simulink Version 8.1.0.604 (R2013a).

The example version has the following setting:

Because of this discrepancy, the behavior is expected. Take a look at the documentation here to learn more about this setting.
