I feel like this tweet suggests that the PDF is a polyglot or an embedded second PDF.

Initial impressions says no about being that file a polyglot.

Oh yeah. I have the paperback 'bible'. I don't think that that one is a polyglot, though.

		Can’t you use the tome as a cluebat? I believe it’s a dual use tool, hence a polyglot.

Ah, no, sorry, no polyglots there yet. We'll get there one day, but so far our tooling doesn't allow for it yt.
