I think that you have to actually watch the grand tours to understand why this seems plausible:
Both Pogacar and del Toro (UAE’s gc riders in the Tour and Giro, respectively) are able to keep up with (and even drop) the strongest climbers, and then look fresh as a daisy across the line. Like they aren’t even trying.
This was most obvious when del Toro lost to Yates on the last stage of this year’s Giro, but Pogacar does it too. They start the final climb a few minutes behind the leaders, then match the fastest rider up the climb and then magically have zero fatigue for the final sprint across the line to pick up a few spots. Yates only won because del Toro made a huge tactical mistake of focusing on Carapaz
Everyone else is dying and the riders from this one team look like they could do another stage… and we’re supposed to think that’s natural?
