I'm pretty sure it can't be a simple code. I've noticed that virtually every possible 5-letter word of the form CVCVC or VCVCV will hit some of those pages. Also every word in them (except 'the') is neatly CVCV... or VCVC..., with no clusters, and that's not a real human language just transposed. I haven't counted but I'd guess each letter occurs equally often too. So it's almost certainly randomly generated syllables.
