What does the notation "kg kg-1" for units mean for specific humidity?

I am using a data set from Justin Sheffield at Princeton that includes specific humidity.

Does it mean kg/kg so essentially dimensionless? Because I have seen around specific humidity measured also in g/kg, maybe that was wrong? These two pages give the same definition of specific and absolute humidity, I thought they were different things:
