As the main text we give the definitely correct slur of EE. The slur of GC is not accurate and, when read literally, it only embraces three bars, which is what we can see in GE. Moreover, GE - just like FE - has the slur moved to the bottom and placed under the note heads. That revision, typically introduced by engravers, is not without influence on the meaning of that articulation mark.
