Because, being mirrored, and therefore identical in contents, Oracle deems it unnecessary to mention the 2nd group when recording log switches. If it switches away from a group, it switches away (by definition) from all members of that group.

Incidentally, 2-way mirroring is a bit brave. 3-way is more robust.
