Because PS 1.0-1.3 cannot do dependant texture reads. Basically, you simply cannot change the texture coordinates in the PS, it's just not supported. On the ASM level, all texture reads must be performed on unmodified texture coordinates.

Correct me if I'm wrong, but wasn't that issue corrected in PS2.0 and higher? I'm (unfortunatly) not at home and can't look at my shader codes, but it seems I had done something like this with a higher version.
