I don't see how "neutralizing" an adversary who you refuse to work with, when it's the winning move, with no teammates up the road and only a chase to keep at a distance, is anything but wheelsucking.
If I were Remco the moment I established the break with Roglic on my wheel, but who refuses to pull through, I sit up and watch his next move. That's race intelligence. Roglic wants to have cake and eat it too. The only thing naive is continuing to effectively do the work for him, not expecting him to contribute to the pace in that circumstance. He refuses to, fine, then you refuse too, calling his bluff. If you then get caught, the whole world sees Roglic's negative riding is to blame. Yet Roglic would know his tactic at that point no longer works, appart from making him an unpopular wheelsucker, because if a large group comes back, it's no longer manageable and so it would be better to work to not get caught instead.
Roglic, however, thus far has been fortunate in finding willing accomplices that catered to his game. Hopefully Remco won't be one again at the Giro.
