Many new worlder have Sephardic Jewish roots (especially Puerto ricans and Mexicans, I match many of them as 4th-6th cousins). Sephardi Jews are shown as mix of Italian-Western Asian- Iberian- Ashkenazi (because many Ashkenazim, probably from the reference group as well, have some Sephardi admix and in general both groups are quite similar) and North African so Mexicans with Sephardi ancestry will score some Ashkenazi.
