Medical appointment questions aligning with PIP questions

Has anybody else noticed a parallel between the kinds of questions asked at medical appointments with the key areas covered on a PIP form?

I have recently attended two hospital appointments, one with a Consultant, the other with a specialist Nurse, and both times they asked about or talked around areas that are covered by the PIP award form. In the subsequent letters to myself and my GP, their assessment of these were recorded, e.g. EDSS scale; any particular difficulties experienced, any daily living and mobility aids used etc.

It makes me wonder if medical appointments are being used as an early unofficial assessment for PIP and other benefits claims... or has this always been the case? It has been several years since my last medical appointments so I don't recall what happened previously.
