That's used only for Google+ for sure, and I suppose HaxSync does it that way as well.
The ID is called your "profile". See "The User Profile". You should avoid changing it.

In my Sync Adapter for Android 4.0 and above, I want to create a "Me" account like Google+ and HaxSync are successfully creating.
Googling all day long, I could find no way to identify this specific contact though. Is there a documented way to create that entry?
