"Disparaging" prior art does not automatically disclaim scope. Previously it was good practice to characterize prior art for its strengths and weaknesses - particularly weaknesses. Then some judges decided to read the specification into the claims and say that the the inventor must have meant to only claim less than was claimed. Another problem with characterizing prior art is that you might be in error when you say some prior art device has some specific weakness or limitation. Maybe that was covered on page 201 of the prior art and you didn't see it. You could be accused of hiding the ball and otherwise misleading the examiner. In fact, even calling something prior art is a no-no. There may be a technicality of dates or non-analogous fields that makes it arguable that a specific reference is not actually prior art. Unless you have said it was prior art - then it is admitted prior art you are stuck with.
So, to generalize your question - can disparaging prior art, or other "patent profanity" spill from one of an inventor's applications into another related application? My view is that it wouldn't make sense but worse twisting of the patent laws/rules have happened.
