In your video, "hi, i'm steve", is he Steve or is he NOT Steve? Because in the beginning of the video, you (he) said, "I'm in a car. It's in a tree. Just kidding, my name's not Steve." But at the end of the video, you (he) say, "Bye, I'm Steve." (I am sorry for this retelling, obviously you already know this.) This contradicts with what you (he) said in the beginning of the video. So is he Steve? Is he not Steve?
it seems like "hi, i'm steve" is sort of like a catch phrase he says. "bye, i'm steve" would be the goodbye variation of this catchphrase
