"Qualified distributions from a Roth IRA -- that is, distributions that are free of tax or penalty -- must meet a two-pronged test. Reaching age 59 1/2 satisfies one-half of the test. The other half consists of satisfying the five-year holding period. Each time you convert a traditional IRA or other pretax qualified retirement plan to a Roth, you must wait five years before you can withdraw it without tax consequences. Consequently, even after age 60, if the account has been open for less than five years, a conversion withdrawal is subject to a penalty."
I'll check further, but it implies that the 5 year rule still applies after 591/2.
