Playmat for 2nd Edition - use with 1st Edition?

By cmdrcody, in A Game of Thrones LCG

What I'm asking (because I can't see enough detail on the 2E playmat, and I don't play the 2E) is are their mechanics / areas reflected on the playmat that are different than the 1E?

The only difference is that it says “faction card” rather than “House Card”. Otherwise the two editions of the game have an identical play layout.
