Three-Phase Transformer Tutorial

I'm working my way through the tutorial (nice job, by the way), and I've come across a little snag. In the 3-phase transformer section:
Three-phase transformer circuits
for the Y-Y configuration, why is A connected to C and vice versa while B is connected to B? Wouldn't this wiring configuration reverse the phase rotation of the secondary circuit? Shouldn't A be connected to A and C be connected to C or at least keep the cross connections in the same order to keep the same phase rotation? Perhaps I have a basic misunderstanding of the underlying concepts. All I know about electrical circuits comes from this tutorial and one college circuits class (15+ years ago).

Thanks in advance,
