Comment (by cauchyschwarz):

 It seems to be related to this piece of code:
 {{{
 else if (ac->oc[1].m4ac.ps == -1 && ac->oc[1].status < OC_LOCKED &&
 ac->avctx->channels == 1) {
             ac->oc[1].m4ac.sbr = 1;
             ac->oc[1].m4ac.ps = 1;
             ac->avctx->profile = FF_PROFILE_AAC_HE_V2;
             output_configure(ac, ac->oc[1].layout_map,
 ac->oc[1].layout_map_tags,
                              ac->oc[1].status, 1);
         }
 }}}
