Oh, yes I completely misinterpreted that sentence. Derf. I was led astray by the coincidence that CEST is +0200 and CET +0100.

My favorite part of that Wikipedia article is this sentence:

"Sie darf nicht verwechselt werden mit der international üblichen Abkürzung der Zeitzonen, nach der 2 Uhr MESZ als 0200B und 2 Uhr MEZ als 0200A bezeichnet werden."

Which is to say (IIUC) that the international standard is that the first occurrence is B and the second is A, exactly the opposite of the German system. O Weh!

I think they just caution you not to confuse the "A" and "B" times with the (military) letter zones A through Z.  The fold disambiguation seems to be in the natural A first, then B order.
