Throw is used to transfer the potion. The recipient still has to drink it. That's how potions work.
That would make the most sense, however at the moment one can transfer items no matter the distance and for no action point. If Magic Pockets were disabled during combat, that sounds like a brilliant idea.
However, I am pretty sure healing by throwing isn't designed to be that way, per say, but is the result of how systems were designed. Making it so a thrown healing potion is transfered to the inventory would make sense (logic and gameplay wise) but would be an exception in how the item is supposed to work system wise.
