To me it just sounds like a really inexperienced person who doesn't yet have the confidence or judgment to handle nuance. When a therapist feels uncertain about a boundary issue like giving hugs, they could say "you know I will need to reflect about it and we need to talk about it" or somethinwg like that (and then actually reflect, take it to supervision or to their own therapist etc.) and get back to the client and discuss the client's perspective, not wonder "oh jeez what would my dentist do?"

In general, I don't have a lot of time for people who need a rule of thumb for everything.
