I actually read this paragraph and got very confused. Maybe a drawing might help. I understand that both most have equal part of swap hive and atx, but didn't get the surplus of value versus amount of token.

You might or might not have noticed, that from the picture above, the pool has around 2049 SWAP.HIVE, but "worth" indicates only 3237 SWAP.HIVE... how come you may have asked? (and for the ones that didn't yet got this... a pool has to have equal value on both sides of the pair, hence if we have 2049 SWAP.HIVE, then 1188 ATX at ~1.72 SWAP.HIVE/ATX, is the 2049 SWAP.HIVE, and so we should have total worth approximate value of 4098 SWAP.HIVE instead)
