Do health % runes stack with Vladimirs passive? If they do, how?

There's a rune that gives you 0.5% percent bonus health. Vladimir's passive ability reads as follows:

Vladimir gains ability power equal to 2.5% of his bonus health and bonus health equal to 140% of his ability power. These bonuses do not stack with themselves.

My question is, how do these both stack together? Do you get greater health bonus for ability power? Or do you get more health except the passive which gives you more AP?
