git log vs git diff vs --name-status

hi,

$ git diff HEAD --name-status M dir/foo1

then i commit this change, and git log says:

$ git log --name-status -1

    foo

M       dir

only. no /foo1. also is the file is dir/subdir/file1, then only "M dir" is shown. is this inconsistency expected?

yes, i know that using --stats this problem could go away, but i speak about --name-status

thanks,
