Look at it this way. If you dysect the sound of a snare drum, it consists of a (pitch-less) noise component and a (pitched) tone component. The noise component has a short duration, while the tone decays for a longer time.
If you smash the hell out of it's dynamics, the relatively soft tone will be boosted compared to the initial short noise burst. That's what they call "resonance" I think.

It's a convoluted way of presenting a simple idea that you probably already know. The most common and simplest explanation of what a compressor does is make the loud parts quieter, right? But some parts of a sound might suck and should be quieter. Depending on how you set it, a compressor could end up squashing the good parts of the sound and ignoring the bad parts:. Which really means: the bad parts are, for all intents and purposes, amplified, by virtue of becoming more even in level with the rest of the sound. He points to resonances as what could be brought up and pose a problem. This will often be the case, but it could be anything in the tail that shouldn't be raised: clicks from samples being cut off, finger slide on guitar strings, wierd mouth sounds. Even past the tail into the noise floor. Maybe the above was just as convoluted, dunno.
