It is Archbishop Lefebvre himself explaining he often uses hyperbole to make a point. Only dunces like you try to make him literal:
If he did, then it's incredibly irresponsible of him to be so imprecise when people's souls are on the line.
or, rather,
SJ = BS.
+Lefebvre's position and his rhetoric changed over the years, depending on whether or not he FELT closer to Rome or more alienated by Rome. So, in this sense, the Archbishop was not consistent and this was a failure on his part.
