ok, I try to answer this myself...

..when looking on the blizz post about keyclone, it says:
Just make absolutely certain that you're not making more than one keypress (for the purposes of the word 'keypress' this includes a single key press AND release with no delays), or including delays between key-presses with each action.

Essentially, if you could legally create the command as a functional macro within the default user interface, then it should be okay.

This is quite funny, because looking on the first question it seems to clearly says that two keypresses are not allowed, but the second sentence says that 'if you could legally create the command as a functional macro within the default user interface, then it should be okay.' So in the example I given above (where you could simulate the second keypress with a /click) on the one hand you use two keypresses, but it could also be done by macro, so the quote above seems to be a contradiction...
