Final Cut Pro – Copying and Pasting Clips
Where clips go depends upon where they come from.

update
If you copy a clip in the Viewer and paste it into the Timeline, the Patch Panel on the left side of the Timeline controls which track the clip goes to.
If you copy a clip on the Timeline and paste it back into the Timeline, FCP pastes it to the same track from which it was copied. To paste it to a different track, change the Auto-Select buttons. The clip now goes to the lowest numbered track who’s Auto-Select button is dark.
