Oh, right; I forgot.

A short name probably won't capture all 3 things this is a conjunction of:
(1) tmm mode, (2) mark-active, (3) point diff from mark. The last can
probably be dropped from the name, so perhaps `transient-region-p'?

Whatever the name is, the doc string should make 1,2,3 clear.

Also, I don't follow your remark in parens - could you elaborate?
