I don't think there's anything wrong with it. It's a disclaimer and not unlike investing and trading forums people posting DYOR - do your own research.
Also WL and ML are human and sometimes when reviews are written you may feel that there was a connection hence get more out of the session or its not the norm for that lady so it doesn't hurt to signal that for the reader. Poor new to the forum person may think that is the standard and either get pissed or disappointed service wasn'tlike that.
Just my thoughts: )
