Should I tell my principal she's unknowingly signaling something sexual?

So, I go to a small Christian private school (100 kids k-12, the town is generally small too) and today was our first day. We had chapel today (a short church service essentially, but watered down for the kids) and our principal made us recite a verse and do hand motions along with certain words in it. Kinda annoying, but whatever lol. HOWEVER, I noticed that one of hand motions looks a LOT like the signal/physical symbol for a handj*b (idk if you have to censor here, don't wanna get banned). To illustrate exactly what it is, make two fists and place one on top of the other and twist with the top one minimum, and that looks sexual to me. Maybe I'm just dirty-minded and yall are regular people who would never think of it that way. There is a chance we will have to do this in front of the whole school + the families at some point. Grades involved: pre-k, 6th-12th grade. I'm a senior, so maybe I'll be the only one who recognizes it. Should I bring it up to her that some people could take it as a sexual thing?
