Well, it's not as if Alaphilippe finished 33rd. He was 4th, so his legs were not bad, just not super, which is why a teammate at the end could have been useful. In any case, if he started to accellerate from too far behind it was because he was waiting on Pogacar to make the first move, but Tadej didn't have the legs and this seems to have cost the Frenchmen the lead trio's wheels in the decisive moment. I'm not for utilizing riders in any scenario that "probably (but in this case definitely) would've lead to nothing," for which I'd have held on to Evenepoel to at least be of prossible use to Alaphilippe in the end. If Evenepoel still failed to be of use there's no real loss, because as things turned out Remco could not have been any less usefull to Julian when it really mattered.
