"A8" is the most significant bit of the address, so both 0 and 1 are valid values and they will write to different addresses. That is how the chip addresses the entire 512-byte address space, since 8 bits would only allow for addressing 256 bytes.

It's not stated very clearly in the datasheet so I can understand the confusion.
