Autohotkey Loop function legality for movement keys

Greetings,
As the title says in regards to wow, how is the loop function viewed when use solely for movement keys I.E w,a,s,d, and space.
so something like
~Space::
IfWinActive, World of Warcraft
{
ControlSend,, {Space down}, ahk_id %wowid1%
ControlSend,, {Space down}, ahk_id %wowid2%
loop
{
getkeystate, state, Space
if state = U
break
}
ControlSend,, {Space up}, ahk_id %wowid1%
ControlSend,, {Space up}, ahk_id %wowid2%
Return
}
My thought is that keys do this by default in and out of game, so as long as I'm not using the loop function to say spam 1 over and over
there shouldn't be a problem with blizzards 1 button 1 action rule.
I wanted to get some feed back on it from the boxers on this forum, as I haven't boxed in years and the last time I did I used pwn boxer
so programing my own scrips wasn't even a thought.

If the loop function of AHK is required to mimic movement as if you were holding down a key, then I would imagine it'd be just fine, since, like you say, you aren't using it to loop in-game character actions.
