Yes it does. You can use it on the tank, and cast spells on the tank, and they get that 40% extra healing.

You can use it like the old Divine Seal/Largesse abilities, except that it's only single target.

The number of ASTs that don't know this is a bit shocking. I guess they should clarify the tooltip a bit.

So if I put this on the tank, would all my healing spells cast on the tank, get a 40% boost?

Better question: Does the person you bond with receive said additional healing if it's also cast on them.
So as a more direct answer: Yes to both questions.
