The body morph pak is not needed for the male morph pak to work. What is needed are the sr1 updates (only two are actually "needed", the base and the head, but all are recommended). The male morph pak loads [injects] into channels that do not exist in the pre-sr1 cr2, thus the need for the sr1 (blue circle) cr2. The male pak head poses, in addition to a few added by the male pak, call morphs that are only included in the head morphs pak. Also called are files included in the sr1 update for the head morphs pak, morphs that do not exist in the pre-sr1 distribution.
