This is about the zeroing variables bug in UE, and yeah, the devs said it will be fixed in 4.7.3. 
However, you quoted my post about the pull request I’ve made (https://github.com/EpicGames/UnrealEngine/pull/923 ), and it’s not related to that bug. It’s a new feature that I propose for the engine, to expose owner-only variable replication to blueprints, in addition to regular replication and repnotify.
