IMO there is no "short"--the pos touching the neg. Fuses are not blowing and wires are not melting. It does seem the pos of one is touching the pos of another. Can't tell about the neg side, but often that is "common" anyway.
I think your confusion is more semantic than anything.
A short just means two things are connected together directly, most commonly things that shouldn't be connected together. Those two things don't have to be power and ground, though that's certainly one common situation where the word is used. Obviously in this case it's not shorted to ground, but to another positive line somewhere.
An open is the opposite of a short--some connection that is disconnected, most commonly one that is supposed to be connected.
