Pogacar never pulled solos ike remco on rolling terrains. In fact the only rider I've seen doing it is Van der Poel, but he's often fading at the end like in Tirreno last year where pogacar and van aert finished in the same minute.
On the contrary Remco is constantly increasing the gap on the chasing groups (San Sebastian, Tour of Poland, Tour of Denmark, Coppa Bernocchi, ...) and I can only remember 2 "fails" since he began: Germany 2019 where Nibali/Thomas and some motorbikes helped a whole peloton to catch hime after a solo of 100km, and Burgos 2020 where his team asked to stop his effort because he only had 20" on a full peloton, wasting energy before the queen stage.
Overijse race last year was the best example, resisting for more than 1h30 to an entire peloton with >6w/kg is just crazy. And before that Alaf/Wellens had to let him go because he countered when everybody was already "à bloc" (his trademark, attacking when the other riders are at the limit like in Valencia, not possible in Algarve)
Outside of the high mountains, Pogacar can lose a GC if Remco has a gap. It would require an amazing team to avoid it. But unfortunately Evenepoel may be afraid to try during his first races against the slovenians, wasting his best weapon (and if the slovenians are smart they won't favor tough races outside of the mountains in order to keep the extra percents required to jump into Evenepoel's wheel like Collbrelli did)
Edit: and let also remember that at last year euro, a "not 100%" Evenepoel catched a "not 100%" Pogacar in the attack then dropped everyone except a 120% Collbrelli. Exactly the kind of scenario he needs
