Short answer not at all (yet)
EG had the easiest group in recent memory with 2 out of the bottom 3-4 teams at the tournament (Fpx and T1) so making it out of that group doesn't mean they've overcome the curse.
Will the curse be lifted if they were to beat Edg?
Probably
Conclusion: EG will lose to EDG and the loser of Drx/Blg keeping the curse alive
