According to Geneticist David Reich these models are WRONG. They are very "low probability" only 5%, and are "increasingly implausible". He is saying that Neanderthals may have up to 70% modern human DNA, rather than there being an introgression event.
The most commonly reported scenario is the modern human mtDNA replaced Neanderthal mtDNA (late Introgression hypothesis) but a second scenario is that some Neanderthals always had a modern human mtDNA (Deep structure hypothesis).
The HST (Hohlenstein-Stadel) sample from southern Germany dates to 125,000 years ago and has a deeply divergent mtDNA that is closer to modern humans but also different than Neanderthals....
The Scladina Neanderthal lived around 120,000 years ago but had the the more common modern human mtDNA. So it is very strange that these two lived very close in time and place but had different mtDNA.
Highly Compelling
