Although the lyrics can be taken at face value, as Cynothoglys points out, that it's about someone with schizophrenia or multiple personalities.
But I also take it as a metaphor for Wire's incredible artistic growth from 1977-1979, this being the final song on the final album in that great run. Newman and the rest of the band just had so many ideas, being constrained in a "punk" band like Wire wasn't allowing them the artistic freedom they needed.
