Here's one example:
Play style Rock Boogie. Hit ending number two. See how the sound naturally decays, or fades away after the ending?
Now play ending three. It cuts off like you pulled the power plug on the entire band.
There are others similar. Listen ending three on Standard 8 Beat. It decays nicely, but then at the end you can even hear it click when the ending stops. Again, like someone pulled the AC cord.
It's not always ending three, but seems to occur more often with it.
