Well, I'm referring to the "RECOMMENDED" part. If the recommendation is NOT to allocate ports 0-1024, then this effectively recommends that a-bits=6. Moreover the meaning of SHOULD vs RECOMMEND should be questioned. The latter is not a regular normative term, and arguably if the recommendation is for excluding 0-1024 then a=6 looks like the SHOULD. If anyone wants the full port set, then a=0 would be an obvious consequence.
