They aren't the same thing since the first is strictly speaking not well defined - see my answer to the OP. I think the problem is that physicists use the same letter, say U, to denote multiple different mathematical functions depending on the context. The "holding XXX constant" thing serves to tell you which function you're dealing with formally. |
