Paired weapons and called shots

[Tor]

If you had paired swords, since paired WP allows you to split your attack to attack 2 separate targets, could you choose to aim 1 sword at hacking off the left wrist and 1 sword at hacking off the right?

If you choose different targets, would this mean you roll 2 separate strike rolls instead of 1?

Also how come there aren't strike penalties? Shouldn't it be harder to called-shot wrists/ankles compared to arms/legs?

Also: if you chose 'neck' and 'head' as your separate targets, would that mean you get the 2 separate rolls, doubling the chances of hitting the required 'natural' number to hit them? Even if it does cap the damage.
