Dynamic Block STRETCH vs ROTATE

[ColinPearson]

So this keeps coming up and I feel like it's simple but I just can't wrap my head around it.  Attached is a block I'm building up. I'm working on all my movement Actions like Stretch and Rotate, then I've  got some other work with a Double Lookup to simulate a multi-Viz Parameter (thanks Libbya from the Autodesk forums!)

 

My problem is with the right top side Rotate.  I want to limit the movement of the object in the selection set from 90° - 135° (assuming 0° is to the right and + is CCW).  It works fine as-is, and also work fine if I stretch the block longer.  However, if I drag the Stretch Grip to the left, then when I try to use the Rotate Grip on the top/right object, the range of travel is flipped or mirrored somehow.

 

Any thoughts would be GREATLY appreciated, this has been making me crazy.
