No it is not. But you are wrong:

    vim -u NONE -c 'autocmd BufUnload * echom expand("<abuf>") bufnr("%")' \
                -c 'vnew' \
                -c 'echom bufnr("%")' \
                -c 'bw! 1'
. You will see
    2
    1 2
. Obviously, that means that current and unloaded buffers are different. You may replace first “echom” with “setlocal” and see that option is set for a wrong buffer. Your autocmd must not be used.

By the way, “bufnr('%')” is almost always different from «"<afile>"». First is buffer number, second is a plain string. Or a filename if you meant “expand("<afile>")”.
