This is another of those mixed up things like Humanae Vitae.   The group that met to decide if Anglicans had valid orders or not decided in favor of validity.  Unfortunately, the Roman bishops in England asked the Pope to declare them invalid so Anglicans would flock to the RCC for "valid" sacraments.   Of course, that didn't happen.   And things got a bit  more complicated when the Dutch Old Catholic and Polish National Catholic bishops started being included in ordinations of the C of E and the American Episcopal Church.  And too, lots of American Episcopalian priests were formerly RC priests.
