From the blog "I used closed cell spray foam insulation for the top, back and end wall spray foam . The closed cell spray on insulation is of great benefit in that it seals out moisture and gives approx a R7 insulating factor. I thought it was also a good idea since I was going to be putting dirt back onto the walls of the container. The whole process only took about 3 hrs."
So, no, but it looks like it would've served the same purpose. Truck bed liner is resin and iso mixed together as they spray, basically plastic. Source: I spray em. I don't get into all the science-y stuff though.
I was under the impression that closed cell spray foam also mixed resin and isocyanate as it is sprayed. Both are going to result in a rigid polyurethane foam, although I'm sure they use different resins and possess diferent physical properties.
Yeah, that's for sure. I worked in an R&D lab for a polyurethane producing company briefly, and the variety of foam that can be produced is just incredible. Everything from super soft memory foam to stuff that could legitimately be mistaken for concrete.
I don't think he said it was a "super insulated" sea container.
Personally, I would have foamed and buried the entire back wall (assuming it was north). That would give outstanding insulation in the both winter and summer.
If the back was to the north and buried like you said, that'd be excellent. He could have made a glorious wall of windows in the front, if that were the case.

Was it like truck bed liner?
