Yes, I mean, I'm not going to go into a full on about the dynamics but you're correct that there is objectively only one sort of torque on the steering axis that can initiate a countersteer. Now, I can imagine that what's happening is the guy's handlebar geometry is partially converting his downward pressure into a forwards torque, causing the bike to steer, making it seem like his technique works (which it does, inefficiently). Or I guess he thinks he's pushing downwards but is unaware of what his own body is doing? But I can't understand how anyone would do that and not notice what was actually happening to the bars. Do people actually pay that little attention to their own/their vehicle's behavior?

obviously yes
