That's another form of gameplay segregation. What's being asked here is a little different, though. It's about not entering a new "mode" (with its own rules) when in combat.
I don't think there's any correlation. Many games don't use the combat/non-combat abilities segregation but still change the rules significantly when combat starts.
A "recent" franchise guilty of this is Dragon Age (the second, in particular, builds walls around the different gameplay elements).
