POSIX is a set of bare minimum requirements, not a bible for a usable system. It's perfectly legitimate to give guarantees beyond the ones POSIX dictates. A working atomic rename -- file data and all --- is one such constraint that adds to the usefulness and reliability of the system as a whole.
That's all very well, but such a guarantee has never in fact been made. (If you can find something in the ext3 documentation that makes such a promise, I will eat my words.)
