Skarl and Tahm Kench remount interaction/exception

Under just about every crowd control, as long as you fill up Kled's courage bar skarl will come running out of nowhere, kled will jump on and I'll get the health I desire Eg I fill up courage as stuns me, skarl still gives me my health.

However seems to be an exception with his W (in which he eats me).

A rundown: Had 70% courage ish so baited tahm, I filled up my courage bar just before he started to eat me. I heard the sound that indicates skarl is back during tahm's W animation and thought "YES! HAHA!". And then he spat me out and I died, resulting in complete confusion.

Anyone who faces tahm will likely expect skarl to force his way into Tahms belly to give Kled his HP. This inconsistency with Skarl likely gets allot of people killed
