Possibly. I also think he should stop sitting 2nd wheel on the Poggio, he's just eating wind he shouldn't. That matters so much when climbing at 38kph in single file.
Overall, I'm really sceptical about Pog getting it done with a last km Poggio attack. I rewatched last year and you could clearly see MvdP spending time on the Poggio to bring Philipsen to position as if he's on domestique duty. Then he closes a 20m gap in the last 300m of the Poggio anyway.
MVP is definitely a problem for Pog i.e. he's really a monster on that kind of uphill sections like Poggio finale. But he's far from being Pog's only problem: the combination of versatile sprinters and fast descenders is another story, a few seconds on Poggio may not be enough given strong chasers.
