If I'm reading it correctly:
P1 - Bridge full humbucker
P2 - Bridge full humbucker plus neck full humbucker
P3 - Neck full humbucker
P4 - Neck north (slug) coil plus bridge south (screw) coil
P5 - Bridge south (screw) coil only
P1 to P4 are hum canceling, being either full humbuckers or a combination of north and south coils. P5 is a single coil only, so can't be hum canceling..
