Looks like I am right. I added a unique file to the bzip2 host, backed it up, then copied it to a gzip host, and the file was found in the pool during the 2nd backup. I don't think changing the backup compression ratio would make a difference as well. I vaguely recall in the docs/faq/'net saying you could increase it later if you started running out of space... which was the argument for going for lower compression levels at first.
