Correction: It looks like Lazo was an ordinary according to Wikipedia, but like Sean said did not speak up until after he retired. It also appears that he was consecrated in the New Rite since he was consecrated bishop in 1970, so technically, because of that, not a true ordinary either.
With some of these Asiatic consecrations the new rite may or may not have been used in 1970. My guess is that some of these countries/bishops continued to use the traditional rite of consecration, as some of these countries were slower to adopt the changes than Europe and the West. It is hard to know unless we have evidence of the actual ceremony, anything else would be an assumption.
I knew one priest who was ordained in 1970, and when questioned about his ordination, he said that it was half English/ half Latin. With some of these ecclesiastical clown shows, who knows?
