How can we explain such anomaly ? :

This is a pretty old study with not that many SNPs tested.
My guess is the P-M45 is R2.

"For Y-chromosome analysis, we used the protocol proposed by (Fregel et al., 2009a). Briefly, sixteen biallelic markers that charac-terize the most prevalent lineages in NW Africa, Sub-Saharan Africaand Europe (M2, M9, M33, M34, M45, M60, M78, M81, M89, M96,M170, M172, M173, M201, M267, M269) were amplified in three different multiplex-SNaPshot assays. SNaPshot products were runon an ABI PRISM 3130 Genetic Analyzer (Applied Biosystems) andresults were analyzed using GeneMapper 4.0 software (AppliedBiosystems)."



"all the samples were first typed for the phylogenetically basal M89 marker, the three most frequent North African markers (M78, M81, M267) and M269, the most abundant European marker. The same five markers were also replicated in the Porto lab using a first multiplex SNaPshot analysis (Additional file 3). Samples derived for M78, M81, M267 and M269 were not included in further analyses; those derived for M89 were subsequently analyzed for the M9, M45, M170, M172, M173 and M201 multiplex set; and ancestral ones for the M2, M33, M34, M60 and M96 multiplex set." https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2728732/

Thanks but still R2 would be surprising for such isolated berbers
