Unix permission problems with 'attrib'

Looking at the source I found something suspicious in "sources/smbd/dosmode.c" in file_chmod.
/* if we previously had any w bits set then leave them alone
if the new mode is not rdonly */
if (!IS_DOS_READONLY(dosmode) &&
(tmp = st->st_mode & (S_IWUSR|S_IWGRP|S_IWOTH))) {
unixmode &= ~(S_IWUSR|S_IWGRP|S_IWOTH);
unixmode |= tmp;
}
So if we do an "attrib -r" I guess this function would get called (I did not check), IS_DOS_READONLY would be false and thus we would preserve the write permissions of the file. This means we would still not be able to write to it.
Would that be it ? Why does it work the second time then ???
