[Starcraft: HotS] How does Sarah Kerrigan 'respawn'?

You kill her, and 60 seconds later, she pops out of a hatchery.  How is that working, exactly?  The Zerg grow a new Kerrigan body, sure, no problem, Zerg do that kind of thing - but is she the same Kerrigan?  Does Kerrigan's soul (for lack of a better word) psionically relocate to the new body?  Is her mind/brain located in Zerg hatcheries and projected out to control her host body Overmind-style?  Are the new Kerrigans straight-up clones with copied memories, with the original long since dead?

(And for that matter, if Kerrigan can clone herself, why doesn't she make an army of Kerrigans?  Pound for pound the Queen of Blades is scarier than any other Zerg combat form...)

Kerrigan's body is her own, there are no clones. When she has been sufficiently damaged in combat she deep tunnels back to the Swarm's main hatchery. There she is placed in a caccoon and regenerates.
