Furthermore, I'm not sure if encouraging plural personalities is the best choice for people with DID (a massive asterisk here, though, as I'm not familiar with the specifics of the disorder - if that actually is considered appropriate by the psychiatric community, disregard that point).
I recommend watching the video Lumi linked. As for the terminology, its a useful way to talk about groups of personalities in one brain, one that shouldn't be abandoned if it allows us to better talk about the phenomenon.
I wouldn't be opposed to referring to a cluster of different personalities as a personality system. Referring to the person in which they are contained as a system is not appropriate or necessary, however.
