Infernus' Ult is not interrupted by stun - is it intentional?

[Suthir0]

Match ID 33570053
Around 21:25 Infernus starts charging his ult, then is stunned by Talon's owl, and the channeling is finished nevertheless. Is it intentional? What stun is then for?

Infernus ult does not get interrupted, just has a delay before it goes off, even if you get CC
