Yes, this is key. Based on all that has been written by the leading Iodine doctors (Flechas, Abraham, Brownstein) you really need 12.5 mg/day of Iodine *at a bare minimum* to treat female issues (FBD, PCOS). Overall it seems that Iodine supplementation at doses far greater than 3 mg/day outweigh the risk of causing thyroid issues.
However Dr. Haskell reminds me of one important point: always do thorough research prior to taking any supplement in doses that far exceed RDA, and look for potential side effects. For example in the case of iodine if one doesn't take companion supplements (selenium, vitamin C, ..) the results might not be pretty. Knowledge is the best form of insurance.
