How is AXI addressing scheme work for this problem?

Hi, I am not confident about my thinking so wanted to clear it.

Let's say  DATA_WIDTH= 64 bits

                AWLEN=3

                AWSIZE=1 ( 2 Bytes data transfer)

                AWBURST= FIXED

According to me on every transfer data strobe will be in WSTRB= 00001000 (I.e. only address x03 will have valid data). So there will be transfer of only 1 byte even though the request is for 2 bytes transfer. This is due to the unalignment of ADDR. 

Please let me know is this correct implementation?

Thanks,
