I read the same thing and asked the same question on Photonet a while back and everyone seems to confirm that it is correct. I too use a print washer but learned that I can put the prints in the washer and let them soak, then run the water for a few minutes, then let them soak again etc. instead of running the washer for a couple of hours steady, using a lot of water. Apparently the soaking leaches out the fix and a few exchanges of water will do the trick. It seem to work.
