'employees_tables' is a data frame object and a for loop through a data frame will just return each column name in the data frame. Hence here the for loop is being applied to the 'Tables_in_employees' column to enable looping through each value in this column - which are the table names. The statement tables=employees_tables['Tables_in_employees'] saves the 'Tables_in_employees' column from 'employees_tables' data frame into 'tables' as a 'series' object . Using employees_tables['Tables_in_employees'] directly as a collection for the for loop would also work.
