And the mtDNA genetic research I referred to was published in 2004, after that 2003 article you linked: No Evidence of Neandertal mtDNA Contribution to Early Modern Humans.

From your source:

However, these results do not definitively resolve the question of a possible Neandertal contribution to the gene pool of modern humans since such a contribution might have been erased by genetic drift or by the continuous influx of modern human DNA into the Neandertal gene pool.
