(I redid the 'NB.'s to distinguish between Michael Day's text and AoC text.) Be careful here: a key phrase is "until they can move fully into a room". Basically this is a restatement of the constraint that amphipods cannot move through each other, and a statement that each amphipod only moves twice.
