Those photos show a lot sealant. The instructions specify bead widths, they are substantially larger than I’m used to, guess that Japanese machining isn’t as exact as the Germans.
They’ve been updating the procedure, looks like 2/13 is the most recent. I like this part. Those pictures aren’t fake, they know exactly what’s happening.
Page 31 of the 2/13 update is pretty good too. Lots of yellow highlighter and bold “carefully”. I think they found the problem. Their technicians.
