Correct, Those are two different examples, the first one just shows how to use the Output Field Separator(OFS) to specify exactly what goes between each field, the second one just shows how to output the fields specifying a character or characters to place between each field without using Output Field Separator(OFS), so when you piped the first one into the second one the spaces you created between each column in the first one are dropped and it outputs the ',' and ':' between the columns.
Using the second awk example(awk '{ print $1","$2":"$3 }' f1) you can specify something different between each column( space(s), comma, colon, slashe(s), etc.
