I don't think merging is an accurate term here. Merging makes me think you take the union of both. But in this case you have two DOM structures and want to make one exactly like the other. And morphing is a good term because you want to change it into the other, not just replace it.

The difference is that with morphing they take the trouble of maintaining focus, event listeners, etc.
