Comment on the difference in meaning between the sentences in these sentence pairs in a similar fashion to what has been done for A1 and A2.
A1 Although they did not win the game, they came out on top tactically.
A2 Although they came out on top tactically, they did not win the game.
The sentences do not have the same information in the dependent clause and in the main clause. The information in the dependent clauses is a bit less important than the information in the main clauses. So in the first one it seems more important that they came out on top, and in the second one it seems more important that they did not win.
