This instruction is a little weird. When accessing memory, the 128-bit operating size of the instruction only loads 64-bits. Meanwhile the 256-bit operating size of the instruction fetches a full 256-bits. Theoretically the hardware could get away with two 64-bit loads or a wacky 24-byte load, but it looks like to simplify hardware they just spec'd it that the 256-bit version will always load the full range.
