^That's the difference between cast time and channel. Channels can be interrupted, but cast time can not, except by death (they will still be on CD though). It's always been like that.

PS This can make for big plays if you know how to time. I once interrupted a Warwick ulting me when I played Riven by using W in the .25 seconds before he ulted me.
