Windspeaker's blessing on Vladimir

A few days ago i tested if Windspeaker's actually works on Vlad. I wen into a custom game on Howling Abyss leveled q to 2 took 3 turret shots and when i had windspeakers in i received better healing. I did it twice and it looks like the keystone works on the reworked vlad q.

Neverthless i have been told that it doesn't several times and I'd like you guys to help me in this matter. Has anyone else tested it? Does it work? Does it not?

Edit: I know it's supposed to work on all healing it's that it didn't work on the previous version of Vlad.
