You can interpret UEC RR however you want. I'm just stating facts, while you are trying to get in the mind of Pogacar, and guess what he was doing.
About my confidence. This is De Ronde van Vlaanderen, not Lombardia. Total elevation is 2.000 meters, and the Oude Kwaremont is 2km's long, but only 500m are a bit tough. There's a reason why MVDP is able to match Pogacar here. When you do a lot of long climbs, UAE is able to completely suffocate everyone, and then Pogacar attacks. Here the climbs are much shorter. I have no reason to believe Evenepoel will get dropped if he's just able to position well, and not lose unnecessary energy.
