I don't have one of these out of circuit and it's behaving badly. How are the 3 bases connected internally? I'm referring to one of these

Are 2 of the bases connected together (internally)? Just puzzled why a 3 base is needed... seems you could do everything with 2 bases. But clearly I'm missing something.
Thanks!
