Would it be something to do with both moving together relative to the environment.
It might get a bit long-winded, as is my wont when we get onto technical stuff, so bear with me.
First - have a look at a quick bounce demo - this is a sample from an idance.net lesson, so it's a tad exaggerated for teaching purposes. Important things to note: the bounce is on each beat, they bounce down into the ground, then back up (not t'other way around), they bounce with their whole bodies - feet, ankles, knees and hips are all flexing to achieve the bounce - and finally, their footwork does not change the bounce, so whether they're doing single time or triple steps, or anything else, the bounce remains the same.
Whew. On to some of the actual benefits.
1) it drives the movement in the dance. Try an experiment - stand normally, pick one foot up, move it forwards, step on to it. Now for the bounce method - sink down a little into the floor (as in the video), and as you bounce up again, step forward. In the first example, you have simply taken a step, but in the second, you have powered that step by the bounce, and you still have momentum from it, achieved with very little effort. The bounce drives the dance, and with practice, lets you dance with minimal effort at very high speeds by allowing you to work more efficiently off the floor.
2) Connection. In simple terms, the follower will match the leader's bounce. (in reality, there's a little more give and take in that) Because of this, and because the bounce is a nice smooth one, one can maintain a connection that is just as clear as if one is standing still. It also lets you lead the timing of steps - if I have no bounce, and am effectively gliding, it's much harder for my partner to know when I'm stepping. With a bounce, she can feel it far more easily.
It also gives me a much more powerful lead with far less effort involved - to give an extreme example, if you want to push, say, a car that is stuck, you don't stand up straight with straight legs and shove it with a purely lateral force. Instead, you sink your whole body down into so that you can work more effectively against the ground. The bounce gives (in a much more relaxed fashion) a similar way of working off the floor to give a smooth and relaxed yet powerful lead. Vital at the kind of speeds Lindy can get up to.
I've turned that into a bit of a lecture - sorry about that - but for anyone who's still reading, I hope this makes sense.
