Weird question

A student asked me today about how to get Minitab (our statistics package) to make a certain type of graph. She wanted it for work or something. So I said to bring the data to my office, and I could show her how to do that. She asked "Are you able to do that, if it's not for class?" It was the "able to" that got me. If she'd asked if I was willing to do that, it would have been a natural question (although it would have been pretty clear she didn't know me well.) But "able to"? Like the dean was going to come by and find out I was helping a student with an unauthorized assignment and dock my pay.
