No its pretty clear, Odin vanquished his foes, then sent the branch off on its own away from the tree, after a while the foes came back so Odin sent his Valkyries out to seek out the latest great warriors to send to Valheim to deal with the foes, rather than direct to Valhalla.

Odin is rather delegating than attempting to kill off worldly warriors, he wants the best to help fight at Ragnarok, not rid himself of strong warriors.
