ok, after watching the full video I think it can be expressed in more than one way. The birds who do not return in the spring (who also migrate south) are a subset of the birds who migrate south. However, since we aren't supposed to incorporate real world knowlegde into these arguments, I guess it can't be assumed that all birds who do not return actually flew south. In this hypothetical there may be birds who flew in other directions.
