Aside from their having matching turned off at the Y-DNA12 level, someone might match you at a higher testing level but not Y-DNA12 because the genetic distance is more than the amount allowed for Y-DNA12 but not the higher level.
For example, kit B193 has mismatches with kit B175 at DYS393 and DYS385. Each mismatch has a genetic distance of one for a total genetic distance of two. This is more than the amount allowed for a Y-DNA12 match. However, they do not have additional mismatches on the Y-DNA13-25 panel. Therefore, the genetic distance for their Y-DNA25 match is also two. As a genetic distance of two is within the limit for Y-DNA25 matching, they will show as matches in that category.
