Chuck, The coating opposite the entrance to the bulb was degraded to the point that it was missing over a large area and the tiny particles of loose Teflon were free to move about in the bulb. (Rolling the bulb you could see a little pile of particles moving about) Since a majority of the hydrogen atoms entering the bulb impact first at the opposite end that would cause a large majority of the atoms in the correct state to be perturbed as well as recombine into molecules. So since the end needed recoating it's best to do the whole thing.
Per the question of aqueous dispersions here is an excerpt from Dupont: DuPont™ Teflon® aqueous dispersions are milky white dispersions of PTFE particles in water, stabilized by wetting agents.
