I can't speak to whether it's intended, but I agree it's not good.

Sounds good to me

I haven't used that much, but so far it does what I want; change the
current window to display the previous location.

If I want to preserve the current location in a window, I would first
move to a different window; I haven't tested to see if that works in the
one buffer/two locations scenario.
