From how it's described in the novels and in ESO, it's a bit more complicated.

When an Argonian dies, their sould travels into the Hist. The Hist then gains their memories, to be passed on to future generations if there is great need (i.e the Hissmir Hist showing the Vestige how to power the city's defences with Hist Amber to repel the Dominion attack), but it's not reincarnation. The soul goes into the Hist and essentially becomes part of it, it does not go into a newly hatched Argonian so far as I know. Each new Argonian is a new being.
