Double-melding is certainly a VERY effective item-sink but I would say that it's a terrible gil-sink since it doesn't actually do what gil-sinks should do: remove currency from circulation.
For items because of player inconsistencies (market flux) its safe to consider each and every item its own currency that can be converted between other currencies.

So just like in the real world (lame comparisons to real life, everyone falls asleep .. . ) when you convert Dollars to Yen or Yen to Dollars you get a different "market" but it is still a currency. You may buy into materia currency and then resell that same materia currency back into gil currency at a better price.
