does my dream self count as an alt account?

i have no recollection of some of the matches "ive played" so im 99% sure its him. i watched the demos back and he only plays spy and whispers comms like james bond. sometimes he will pretend to be a spy on the other team disguised as a spy on my team.

the problem is hes doing way better than me and people are starting to recognise "me" in scrims even though its definitely not me. i tried explaining this to my team but they think im dodging demo reviews. so now im stuck trying to decide weather i need to submit a ticket to the admins telling them my body is my main but my demon is an alt. we technically share hardware but not a soul. i dont want to get banned but i also dont want to start an argument with him in case he does something to spite me.
