Potential Bug with Lee Sin's Q.

Its a common mechanic to be able to flash during an ability's animation. This is most commonly seen on champions like Ahri (Charm) or Braum (Winter's Bite).

While practicing Lee Sin's Ult Flash/Insec Kick I realized that it plays off the same concept, flashing during the ability's animation. So I decided to load up a custom game and see if the same thing could be done with his Q. The results are fairly interesting. Lee Sin's Q appears to project from wherever he was before the flash occurs, unlike Ahri's Charm. I have tested/practiced this mechanic with several champions (Ezreal, Zed, Xerath, Riven) and so far Lee Sin is the only one I've had a problem with. With each of the other champions, the skill is projected from the position after the flash, in the direction of the cursor before the flash.

Some of the videos picked up my skype audio or other tabs audio, feel free to mute, sorry.

Can anyone explain why this mechanic does not work on Lee Sin's Q?
