Yes, it does. I remember some people going Windspeaker's on Nasus (because they want the 5% CDR and don't want the other 2 keystones in that tree) and getting a ton of extra lifesteal. It also works on spellvamp and self-heals too, for example, Vladimir Q.

The in-client tooltip is correct; the in-game tooltip is wrong. Heals and shields on all allies including yourself are 10% stronger.
