[GAMEPLAY] Recall Continuing Despite Being Hit

On 3 occasions now, I've hit someone 2 seconds into their recall, but it didn't stop the recall and they were able to base. Only just yesterday i was playing as Olaf with the new Marauder skin against a Project Yasuo , and 2 seconds into his recall i clipped at the max range of my q, but all it did was pop his shield and his recall was uninterrupted. I dont know if they changed how recalling works again but last i checked it was only in the last .75 secs of the recall that you can still make it back to base, NOT 2 seconds. Whats going on?
