'Disengage' in combat resolution feels off?

[Chyttering]

I'm struggling to understand the thinking behind the 'Disengage' option in melee combat resolution. The main rulebook p272 says "Disengage may only be selected if the Unit for which it is chosen has lost the combat, not if that Unit won or drew the Combat."

 

As written, only the losing player can elect to Disengage. If they do so they get an unobstructed move away from combat, can't be shot at, can't be pursued, and don't take any tactical status. Or they can choose to Fall Back, in which case they can be shot at or pursued and have the Routed status. The winning player... can only Hold? 

 

It really feels like they got the text backwards, and the intent was that the winner could choose to Disengage, but the loser, even if passing a test, could only Hold or Fall Back. Or am I missing something that keeps this balanced?
