Berdych would top the group courtesy of H2H.
No he wouldn't - Nole would be up 2 sets and Berdych would be up 1 set.
That would require andy's match to be played first on Friday, A) there is no guarantee of that, B) please just stop, Nole would never throw a match
We're discussing the scenario where Andy plays first. And I wouldn't be so certain that Novak wouldn't throw a match - he likely threw one against querrey last tournament.
