When done baling with a little square baler, my uncle would pull out the complete bale that was still in the compression chamber. But he would leave the partial bale because it wasn't much hay. And when switching between hay and straw, you would have to throw away the first bale out because it would be part straw and part hay. But when you are building bales that are between a half-ton and a ton, you want to tie off and eject the partial bale because that can be quite a bit of hay.

In the video, you can see the plunger going back and forth.
