No, I don't think it will return only 1 record as a count. If the original table has multiple Y records per Master_Code it is supposed to return the number of Y records and if it didn't have Y records, IMHO, it supposed to return number of N records.

I'm guessing, now I have to setup a quick test case - I'll do in SQL Server.
If it's not broken, fix it until it is.
