You write: "never displayed any multiple-type signs" - exactly what do you imagine those "signs" to be? It's like saying someone doesn't "look gay" - what's "gay" supposed to look like?
I imagine that the "signs" in question would be the behaviours witnessed at various times in Chris, who is really, the social groups only example of multiplicity. Apparently at times these behaviours (such as personality 'swapping' etc - sorry, I'm not up with the correct terminology) are apparent, I've never personally seen them in anything other than an online context.
Using your gay metaphor - I imagine gay is supposed to look like showing indications of a desire to have sex with people of the same gender. In this case "multiple" is supposed to look like showing indications of having, or believing you have, multiple persons or personalities.
