and the wiring on the manual is pretty weird

is this configuration really better?

and what exactly do the jumper cables do?

Ultimately, they will perform the same. The jumper cable simply wires the two coils together, rather than running a separate wire for each that would connect the coils at the amplifier's speaker terminals.
