I only think the ruse part of the rivalry happened after Snow's curse. Prior to season 3, Hook seriously had it in for Rumple for what happened with Milah. The events of Hook, Rumple, and Milah happened probably 200 or so years prior to the events of Snow, Charming, and Regina, and it was those events that drove the 'rivalry' between them for centuries. They finally reconciled during the NL arc. Now, Rumple may very well have come to terms for his part when he met Emma in the Past, and kept up the ruse for history's sake, but Hook's awareness of events, I feel, only covers the previous year, at the most, and probably less than that, since I think his timeline was untouched until after he regained the JR from Blackbeard.

Sunday could prove me wrong, though.
