Top Guild Tournament Games?

Was looking at Observer Mode earlier.

I get what a Top Guild Match is.
I get what A Hall of Heros PvP is.

What is a Top Guild Tournament Game?

the tournament is what you go in on the way to the Hall of Heroes. You start in Heroes Ascent, and work your way up a series of maps (I believe 7 now) to the final one, the Hall of Heroes. When top 100 guilds are playing in lower Heroes Ascent maps, they show up in "top guild tournament" games.

Ah - I thought that was all covered under Hero's Ascent.
