Yeah, if both the loud and soft sound are played at the same time,
they will both be decreased in volume. When the loud sound ends, the
compressor will ease up on the signal and the (remaining) soft sound
will get louder.

I've found that a good way to get a feel for a compressor is to mix a
drum loop over some soft strings or a synth pad. If you play with the
compressor settings, you'll start to hear the strings get quieter when
the drums hit. You'll start to get that Daft Punk trademark compressor
breathing sound, and it's a good setup for hearing what compression
can do.
