As you've learned, the crossover for a bi-wire capable loudspeaker involves a high-pass section and a low-pass section that are electrically separate from each other. The only way to operate a bi-wire capable loudspeaker is to either use a jumper which intrinsically acts not unlike an audio adapter, with the same type of sonic compromises that audio adapters tend to involve, or choose to use a proper bi-wiring scheme. That said, to use bi-wire jumpers instead of an appropriate bi-wire cable configuration is inadvisable, unless the sonic compromise of bridging the signal is acceptable to a listener.
The desired affect of bi-wiring is not to change the way a crossover functions, the desired affect is to avoid the unwanted effect (think of it as noise, distortion, or "detrimental energy") of a woofer from affecting a tweeter which includes the components of the tweeter high-pass section. When the tweeter and the high-pass section of the crossover is connected directly to the amplifier outputs, the tweeter and the high-pass section are "protected" from the degrading influence of the EMF backwave produced by the woofer.
Here's a link to an article that might provide more insight:
Excerpt from SoundStage! article, Synergizing with Greg Weaver: Biwire or Biamp, Bi Golly!

"...Running separate wires from the amplifier can have a profound impact on relieving the tweeter circuit from the back flush of EMF (elector-motive force) generated by the woofer. When the audio signal to the woofer ceases, such as when a loud bass note is finished, the woofer tries to stop moving. In trying to stop, it actually goes through a process of "settling" because it is too massive to just stop instantly. As it settles, it moves forward and backward repeatedly until it can completely come to rest. During this movement, as the voice coil is moving through the field of the magnet, it generates its own signal. That generated signal is sent backward up the woofer wires and into the crossover, where it corrupts the rest of the music signal..."
