Zay-ES applyChanges

Hello. Does using applyChanges() on an EntitySet affect other EntitySet’s applyChanges result?

For example (Pseudo-code):
Position is changed…

EntitySet (Position, Velocity).applyChanges() returns true
EntitySet (Position).applyChanges() returns ???

EntitySet.applyChanges() only affects that entity set. It makes its values current with whatever the real entities have… else an entity set will never update as its a static view in time (until you call applyChanges()).
