True? I don't see how they would...but then I'm not an electrician either.
Don't see how the AFCI could affect the GFCI, however, it may (I stress 'may' because I don't see how it could) be that a GFCI tripping on a ground fault might possibly, remotely, trip the AFCI - but that would not necessarily be a 'bad thing' either ... just reset both the GFCI and the AFCI if that did happen.
The 2008 NEC leaves AFCI protection out of the rooms with GFCI protection, could be that there could be (a lot of 'could be') some interaction, but all I can see is the GFCI tripping the AFCI if anything 'could be' happening - the GFCI is downstream of the AFCI, and only senses ground faults, so I don't see how an AFCI could ever affect a GFCI.
