The question is whether the specific in this case contradicts the general rule. The specific may do so: it doesn't include the language that otherwise indicates multiple attacks for a ranged attack, and it furthermore uses a single ranged attack roll to apply to multiple enemies.
I don't think there's a perfect case to make either way. Since it doesn't much matter, I'd be willing to let the player choose how to play it, as long as the player chooses before using it and is consistent.

I have an issue with this reading. While it is a personal one, it strikes to the heart of most rules disputes over 4E.
Let's face it - we are constantly arguing RAW vs RAI based off of some rather ambiguous wordings most of the time. For these arguments, the best that we can do is treat the main rules as the baseline and only modify them as per the power/feat/class ability in question.
Let's apply this to
Split the Tree.
Ranged attack wording from PHB270:
Ranged attacks target individuals. A ranged attack against multiple enemies consists of separate attacks, each with its own attack roll and damage roll. Ranged attacks don’t create areas of effect.
One attack roll per target.
One damage roll per target.
Now, let's look at
Split the Tree:
Make two attack rolls, take the higher result, and apply it to both targets.
Knocking some chocolate into the peanut butter, we now have:
Best of two attack rolls for two targets.
One damage roll per target.
This is as far as we can go without a DC25 Conclusionary Jump check. While it is fascinating that they do not have the "two attacks" explicit statement, note that the rules on page 270 separates the attack/damage rolls for Ranged attacks on a
per target basis, not
per attack.
Within my game, however, I have left this up to the Ranger's player to decide (he chose separate damage rolls). I must agree with a previous commenter that it is more important for the game to be fun than to the letter.
