Elaborate? You have a brain, right? Your OE strut/spring set is a matched pair, the compression stroke is related directly to the height of the spring. By switching to say, an Eibach Pro-Kit, you lower the car about 1.3", therefore reducing the compression stroke by 1.3" also. This is not bad, since the new springs are stiffer and don't increase strut travel greatly. Now, drop it 2" or more, with a set of 'rice' style coilovers, and you've effectively reduced travel by over 2", however the compression stroke has not decreased. What happens when the stroke, now being 2" shorter, must accomodate a large bump? It can't, since the total travel is less than what's allowed. You probably hear noises when the car hits bumps and such, what would you think that is? That's the piston reaching the lowest possible point and bottoming out.
In another example, jump on a trampoline. Your highest acheived point , say 6 feet, is equal to the total travel in the compresion stroke. Now, take that distance and reduce it by half, BUT continue to imagine jumping the same distance, 6 feet, as before just not reaching the same height since it's been reduced. You will technically have to hit the ground in order to make that happen. What does hitting the ground feel like?
