I'd like to add more. If you use both amp outputs there's a possibility that there will be a problem, such as a resistive load when both sets of terminals are used which may or may not cause a problem with the amp & again may or may not cause a degradation to the sound quality. Depends on if the outputs will be bridged, on the load impedance, running in parallel & whatever else goes on when you do this.
You could also stack the bi-wire ends at the speaker if there's room & still use a jumper. It depends on the terminations of all involved.
