He’s more than likely referencing Ramses III who was found to be E1b1a;
We amplified 16 Y chromosomal, short tandem repeats (AmpF\STR Yfiler PCR amplification kit; Applied Biosystems).........Genetic kinship analyses revealed identical haplotypes in both mummies (table 1⇓); using the Whit Athey’s haplogroup predictor, we determined the Y chromosomal haplogroup E1b1a
The Distribution of E-M2 and it clades in Central and Southern Africa has usually been explained by the ‘‘Bantu migrations" (which occurred 3000-2500 B.C), in which agriculture and iron technologies spread from the Bantu's homeland located in the Benue complex i.e. Nigeria/Cameroon’’
But their presence in the Nile Valley and in other Non-Bantu speakers Can Not be explained in this way. E-M2 (hence e1b1a) distribution is probably explained by their presence in the populations of the “Early Holocene Sahara”, Who went on to people the Nile Valley in The mid-Holocene era (12,000 B.P.) according to Hassan (1988). Keita and Boyce; Boyce, A. J. (Anthony J.) (2005). "Genetics, Egypt, and History: Interpreting Geographical Patterns of Y Chromosome Variation".
Map of the MODERN E1b1a distribution
Genetic relationship is certain as with all of us, but actually coming from HIS loin is another argument completely that would require more indept DNA analysis that what is currently available.
