Would this pose the problem of loading the krab at a peculiar angle?
Not usually. Assuming the anchoe is artificial as opposed to a large natural belay. Effectively you start with an anchor to which a karabiner is clipped and an Alpine Butterfly is clipped to that karabiner with on side of the rope also passing through the anchor as normal.
So all members of the party except last are abseiling on a rope whcih is clipped to a karabiner via a knot loop. They can use either end of the rope but the one which isn't passing through the anchor would "sit" better.
Last person unclips the karabiner from the anchor and then clips it around the rope as usual and abseils.
