The data Name and genderr are not connected using a data frame. But when I try to retrieve names of males, I’m able to retrieve the names. Is it internally connected?

I was expecting that the two objects must be connected using a data frame, to retrieve values of each other. But here i did not use any dataframe,still i’m able to retrieve. Are they internally connected
