With Possession, it doesn't grant you any control. You just follow them like an Abathur Symbiote, as the ability description says.
I don't believe it would cause too much confusion, if any, due to the fact that the icons are entirely different and Syl's Possession is a talent. Nobody complained when Tracer and Zeratul both had Blink, right?
With Petty Illusions, an attack coming from the disguised hero does not count toward dispelling the illusion. Both abilities and auto-attacks count...
