OMG, that oil filter is slightly ridiculous.

Once a gasket cold flows when it's been in one spot for a while, chances are that it isn't going to seal that well if it's reused especially if it gets moved slightly. I don't see a problem for short term use, as long as the gasket is above the level of oil in the pan so it isn't submerged. The worst that can happen is a minor oil leak. That's a really sweet seal for an OEM application, I'm impressed.
