question about profile MSC:Prevent Loops when pegging Non-Standard Jobs

question about profile    MSC:Prevent Loops when pegging Non-Standard Jobs.   Default setting = yes

Documentation for this profile says:

Yes - If there exists a non standard job demand for a toplevel item in the supply chain bill and the non-standard jobalso exists as a valid supply in the plan, ASCP will make thepessimistic assumption that this could cause a fatal loop inthe pegging and essentially ignore this demand for peggingpurposes. This default setting is recommended strongly toprevent plan failures due to pegging loops.Question - does this stop only pegging or does it disrupt demand explosion altogether.  We are finding some non-standard demands are missing from ascp.
