FAA ambiguity

AIM 3-2-1 says that it is the responsibility of the pilot to insure that ATC
clearance or radio communication requirements are met prior to entry into
Class B, C, or D airspace; the Air Traffic Control Handbook tells
controllers that it is their responsibility to coordinate the passage
through that airspace of flights to which they are providing services. Which
is right??

I don't see any conflict. The AIM tells me that it's my responsibility to handle
things before I enter the controller's airspace and the ATCH says it's the
controllers' responsibility after I get in there. Two different scenarios and
locations in the air.
