Monk Whirling throw vertically. Intentional? or abuse?

[Scruffy6]

Monk Whirling throws states "you propel your grabbed or restrained foe a great distance. Choose a distance in feet of up to 10 + 5 × your Strength modifier that you want to throw the creature. Attempt an Athletics check with a DC of 5 plus the total distance in feet you’re trying to throw the creature. At no point does it say the destination has to be horizontally perpendicular. So as only every second square worth of movement gets classified as 10ft. And the distance is calculated from the thrower. You can throw someone 5 feet in front of you but 10 feet vertically up. This means the target takes 5 points of falling damage and gets knocked prone along with the regular damage of whirling throw.
But it gets better/worse. If you are being attacked by 2 opponents within 5 feet of you, you can throw 1 of them 10 feet above the other foe. that way the target falls on the other opponent and that means that opponent also takes damage. Is this ruling valid RAW? and if it is, is it intentional by the design team? or just something noone thought of and should be fixed in the beta?

I honestly don't think horizontal vs vertical should be distinguished here and I love the sound of a monk throwing a guy above another guy, please leave this in!

Edit: Let me add the caveat that a line should be added that the target being thrown does not take both throw and fall damage, but whatever would deal more damage between the two. No doubling up on damage here.

I enjoy the idea of throwing a guy at an escaping flyer, so I'd very much say this should stay in (it's fun, flavorful, and doesn't seem overpowered--though as zerodarkfire said, a small addition of only taking throw OR fall damage would be in order).
