It's actually a 6-part paper. This is the link to all the sections: http://www.engr.ku.edu/~kuktl/bicycle/Tubular.html

Anyway, as to why one thick layer on, say, just the tire, won't work like thinner layers, one on the tire and one on the rim, I think the answer lies in one's definition of "dried". Tubular glue does not dry completely, at least not in the time he's talking about. There is some slight tackiness there, same as dried rubber cement. That is what sticks the one layer of glue to the other.
