It doesn't make sense at all. If you've spent the 100 currency, the only way to get exactly 100 currency back is doing only the first 3 nodes for 100. Assuming you normally can sim GW anyway, only completing the first 3 nodes is effectively giving up 1100 GW Currency, whatever crystals and shards from the last few nodes as well as the chance for an Omega. Just the 1200 GW Currency alone can buy 3 shipments of ship blueprints. And crystals plus chance of omega is way better than some lame QGJ shards being fed to shard shop anyway.
It's not fake news and is a related issue to something which CG has acknowledged. People used to have something like 25 GW Currency missing because you used to be able to refresh GW shipments for 25. CG GAVE these people 25 currency just so that their currency total can become a nice whole number again. So once again you're wrong, this is a real issue and more valid complaint than most of the other crackpot complaints around here.
