Why does everyone say that a narc won’t dump you if they don’t have new supply?

I don’t find this to be true. Me and my ex narc broke up recently and he doesn’t not have new supply. We have to work together and my coworkers notice that he is still paying attention to me when I’m not looking, and making subtle irritating noises around me to try and get my attention -something that use to work before but does not work now. They are also saying he looks like a train wreck.

I’ve also noticed narcissists get very obsessive and repetitive with certain things. For example a few days ago, I joked about a girl that he use to follow on Instagram, and that night he went and followed her on both of his accounts and started commenting on her photos. Something he wouldn’t have done if it didn’t mention it, as if he planned to do this to get a reaction. The girl still hasn’t given him the time of day. My coworkers say he doesn’t even want that girl but is using her to get me to go nuts.

So is this him trying to find new supply but failing and therefor trying to control me by staring at me? A couple days ago we blocked each other off everything, and I have completely ignored him & 0 eye contact.
