Schema - ability to place multiple XFM features per shapefile object?

I'm trying to do something akin to this:

Criteria A = ([attribute1]<=0)

Criteria B = COMPARE("[attribute2]","True","")

Place cell "Alpha" for Criteria A

Place cell "Beta" for Criteria B

...Knowing that the two aren't mutually exclusive (e.g., if Criteria A and B are true, cells "Alpha" and "Beta" should both be placed).

The response I've seen is the following: 1) If Criteria A and Criteria B are both true, only cell "Alpha" is placed.  2) If Criteria A is false and Criteria B is true (Criteria B is always true), then only cell "Beta" is placed.  I've tried to implement this scenario in a couple of different places in my schema, and each produces this same response.

Any idea why this is?  I'm happy to supply a less abstract example (as well as my schema, shapefile and cell library) if that helps.

TIA.
