If that were the case you would have to also consider the flight time of arrows when shooting distant targets (10+ squares).
Maybe faster monsters should be allowed to move between the moment of the projectile leaving your weapon and the missile hitting its target, if it's so far away?
I think this would be too much attention to detail, though. Simplification works better here, it streamlines the gameplay.
Arrows/quarrels returning take the same amount of time as hitting their target in the first place, which is to say a fraction of a second up to perhaps a whole second.
That is a really insignificant amount of time, hence I don't see how the process should consume more energy points.
Throwing returning weapons like rune-covered trident and some other stuff, doesn't require more energy from you just because it's returning, which is important especially when you consider their size, weight and cumbersome design (when used as projectiles).
Arrow/quarrel is a small, light, somewhat aerodynamic object, I think its current in-game behavior represents this very well.
