You've got it correct. One hose drains water from the outside of the tank in the filler neck area. The other hose vents the inside of the tank through the charcoal canister. That hose is connected to a one-way valve that keeps fuel from running out if the bike tips over.

I don't know which hose is which on your bike. If it is water drain, nothing bad happens. If it is the vent, if you left it open a long time, dirt might get inside and (heaven forbid it) vapors would escape into the atmosphere.
