[GAMEPLAY] Friendly Tahm Kench cancels Vi ult, but it still worked...

So I was playing Vi in ranked and ulted in the middle of the enemy team, but tahm kench wanted to save me, so he used his "swallow-move" and swallowed me mid ult. Then he was dragging me away with the red beam still pointing to the enemy. But as he spat me out I instantly "teleported" in the middle of the enemy team ( even though I was way out of range at this time). Resulting in me dying instantly.

This behaviour cannot be intended.
