I’m not sure I agree with Jeff. Again, looking at a picture makes it difficult, but if the countershaft gear is setting forward of the main shaft gear as it appears, the countershaft gear will exert way more force on the forward edge of the main shaft gear. This is the problem of an off set and what you see in the failed gears. The teeth start to fail at the forward edge of the main shaft gear and the destruction continues until the teeth are gone. I don’t think only looking at the contact pattern in the middle of the gear tells the whole story.
