A kind of pay gap can still sneak in by having roles that are typically favoured by women being less well paid. Also via women being penalised for taking time off to have children (in the US, probably quite a significant thing given the paucity of holidays). And another pay gap that's still quite insidious is when women are passed over for promotion to the next level that has a higher pay grade.
This is not quite as bad as two people doing the exact same job being paid differently, but it can still lead to a pay gap, and some of those factors are worth being conscious of and addressing.
