53 minutes is not very long. Was it a repetitive dive? What was the surface interval time? What was the data from the prior dive?

Yes, there were mitigating circumstances to the oxtox. But that's not the point here. The point here is that he toxed at 1.3, and he did not exceed the O2 clock.
Therefore your reasoning for not teaching Oxtox rescue is completely bogus, close minded, and dangerous.
