They literally admit to this and go on to provide the evidence for their guess:

I know they admit it. I'm just pointing it out, since many of the comments here seem to be taking it as truth.

And they don't provide any evidence. Not a single piece. Merely claiming it's a "solid guess" doesn't make it solid. It's based on nothing. Tracking pixels are extremely common, so there's nothing to suggest it's tied specifically to this. As opposed to, like I said, a buggy bounce detector.
