I think it helps to isolate the issue and prescribe better targeted intervention measures. If we can say that for the same level, gender pay gap does not exist, but there is discrepancy in promoting women to senior/executive levels: and there could be many legitimate reasons. and the issue of gender gap becomes an issue of promoting women to senior levels from the inside, or more diverse hiring for senior job roles from outside.
