Question on Fusing Items

Everyone knows that cubing will only increase an item's rank from Rare -> Epic -> Unique, and never make it go down (ex: Unique -> Epic.)

But does that same rule apply to fusing?
If I were to fuse two of the same items that are both Epic, the potential will be reset, but is there a chance that it'll go back down to Rare? (Or does it reset, but stay as Epic?)

Thanks in advance~
