[...] its more "consecutive weapon attacks" then coming at an opponent with two weapons at the same time.

That is more or less what it amounts to in most cases. Separate attacks are made with each weapon, in quick enough succession for it to happen in a single half-round.

As for being able to use a bow and swing a melee weapon with that perk; it involves having an arrow between two fingers of the hand holding the melee weapon and holding said weapon with thumb and two other fingers so it can be held out of the way to notch and fire off the arrow. It's a unique skill that requires Duel Weapon Finesse (or similar).

The same thing can be done with a crossbow; the difference being that most crossbows require a second free hand to work the mechanism(s) for it to be ready to fire again, and that pulling the trigger is simple enough to be done without the perk (with the normal duel wielding penalty applied).

It's worth noting that Pewwer had a huge penalty to his attack with that bow shot for being in melee range; bigro in fact succeeded in defending against it... just not by enough to negate all the damage (for which Pewwer had an excellent roll - a perfect roll, in fact, if I remember correctly).
