I had professors do different wordings for questions throughout college, I never encountered a professor or TA that wouldn’t clarify if asked, and, generally, the amount of confusing questions evened out across all of the versions, especially over a semester. They usually aren’t doing it to trick students, they just want to make it harder for one student to look at someone else’s test.
There is a risk of it negatively impacting students, but encouraging students to ask for clarification helps a ton.
