As the title says, isn't a pipe supposed to pass the result of the first command to the second command? Going by that, giving a.txt to del
shouldn't be wrong, right?

I found the answer. Looking at the documentation, it seems these two commands run at the same time, so the latter command can't receive the former command's output result. It only works when the second one is waiting for input.

“ dir/b a.txt | del ” has no meaning at all, because the del command does not read data from standard input.
