Not exactly. It's more like the man 'merges' with the sphere, gaining its power and the ability to control it. To quote from official sources:

"To be frank, a covenant is the marital sex of a human and elemental couple, and frankly, a covenanter is also the beloved husband of an elemental. If we think about it like that, then we can say that it is a “covenant” when a dark matter assaults and has sex with a man. And a dark matter grants her own power to the man who became her beloved husband, or rather, “covenanter”. Men who become covenanters become able to freely manipulate the black object, a mass of demonic energy which is regarded as the element of darkness, which dark matters, including the author, ride on, as if it were a part of their own body."

You can find this info, as well as a lot more concerning Elementals, in the  Elemental Handbook, who's translation can also be found on this wiki.
