reseller, people working hard on their sites to get them 'out of panda' are generally hoping to improve the site's quality such that they are no longer affected - I am one of those and consider a 'panda refresh/update' to be the test every few weeks of whether our work has been successful.
Of course, we all hope that the panda algorithm itself will change and release our sites, but that's a hope not something to actively work towards.
Point is, both 'refresh' and 'update' are equally important to people with sites affected and whichever takes place most of us affected would still consider it to be a 'panda rerun'.
ps I have three sites that have been released from panda after having had no changes at all, and a main site that I've been improving constantly for 10 months that hasn't been released (it's much higher quality than the three that have been released), so fully appreciate that just waiting is probably as effective as working hard to improve things.
