Right, Catholics in Maryland favored "tolerance" (they were in the minority after all), Protestants favored "official." I don't think Catholics in British colonies sought anything more than tolerance (not that there weren't Catholic confessional states elsewhere in the New World, such as Mexico).
Maryland Protestants revoked the 1649 religious tolerance act almost as soon as they came to power (they came to power in 1652 and revoked it in 1654; it was reinstated in 1658 and lasted until 1692).

As an aside, the reference in the article to "Unitarians" is an anachronism as there probably weren't any (and certainly none who called themselves such) in North America in the 17th century.
