Piero and Sokolov only reconcile their differences and become allies at the end of the game, in the second-to-last mission. For the vast majority of the game and all we know of their history together, they're antagonistic toward each other and do have a fierce rivalry.

You are right that Sokolov is both an enemy and an ally. That's why he's listed under both categories.
