Transferral Potion Help

[Joddon3]

I have looked through all the Transferral potion tags and couldn't find an answer to this specific question. Keep in mind I am reading the card as is and not misquoting it at all.

Play during any combat. Any "other" player (your choice) fights the monster(s).

this is the line I need help with and i put the quotations around other because its that word that I am having a hard time with believe it or not.
I was in a game of Munchkin (a very competitive game I might add) and a player used the Transferral potion to make himself fight the monster. Now I had just bought the game and before I played I literally read every card including Transferral potion and it CLEARLY states Any OTHER player... if you play the card your not an "other" player. Now maybe the card is meant to be usable on yourself maybe it isn't but if it is supposed to be able to be used on yourself then it really should say "any player" and leave out the word "other". So if someone could help me with this preferably someone who knows the full ruling on the card I would be grateful.
