Can't tell if you're joking, but I think they mean that the positive effects of making the promise are immediate for Macron, but he won't have to deal with the actual cost, logistics, political maneuvering, etc., until after he's re-elected, if at all. Cynically, he could make promises he has no intention of keeping.
It goes both way, isn’t it? Whoever in power in 2035 who will get to cut the ribbon of the reactors will make it like their own victory. Macron’s name and whatever he would do to make it happen will be conveniently forgotten.
