I see what you are trying to say, but disagree. There is nothing about describing conditions that mandates the phrase "other than you" to mean "definitely you".
Let's go back to the feat itself. Assume that you are the DM adjudicating use of the feat, where there is no creature adjacent to the enemy. You ask the player "Are any creatures adjacent to the enemy other than you?" The player says no. Your approach implies that the player has to answer "No, but neither am I", to which I picture the DM (now mysteriously dressed in barrister's robes) saying "Please just answer the question - are any creatures adjacent to the enemy other than you?" And you must answer no.
Please understand me -- the odd phrasing is the reason I suspect they did intend it to be melee only, but it isn't sufficient.
