When you "sign and encrypt" a message or file to somebody, it is
signed with your key and encrypted to theirs.

Your client may be simply asking you to do that, unless they require
separate steps in a specified order that produces different output to
the standard method. In that case, you could encrypt the file to their
key as the first step and afterwards you sign the encrypted file that
resulted from the first step.
