"PSTAT" in "Is It Fall Yet?"

I just finished re-watching Is It Fall Yet?, and I noticed that Quinn and her friends referred to the PSAT as the "PSTAT." Would this be an attempt on MTV's part to avoid getting into legal trouble over the College Board's trademark covering the acronym "PSAT"? I am curious because I remember the PSAT being referred to by its correct name in an episode of American Dad! Might there be some other reason for slightly modifying the test's name?
