Of course they do - depending on operand size they operate on 2-, 4-, or 8-byte quantities. When the second operand is a register, the suffix is redundant (but doesn't hurt), but when the second operand is an immediate, the assembler (in AT&T syntax) has no way of knowing what operand size you mean.
