It's a classic. We got a bunch of those as well. If their reviewers can't find the exact words they are looking for, they are going to reject you in a split second.
They can always find a reason why they don't want you to pass. When I was in the process of launching iOS, I spent a day studying the iOS listing guidelines because of the zap tip problem. Turns out zap didn't break the rules, it was within their rules, and they ignored them. I'm going to share this conversation later.π
