The link you attached lists a few different lead-free solder alloys with the lowest melting at 412F(211C) well above 340F(171C). Eutectic tin/lead solder has a melting point of 361F(183C), also above 340F.
I'm not sure whether or not cracks can heal at temperatures below the melting point, but I would be surprised if that were possible.

A high end home oven will easily swing between +- 25 degrees of the temperature that you have dialed in, and that's if it's well calibrated. If he didn't dial in "340" quite right, and his oven was average, I can easily see it hitting temperatures of 412+, and that could also account for his varied results.
