The lead designer (Chris Avellone), who I think was the primary author of this document, is often playful and energetic/hyperbolic with his language, yet is extremely focused and professional in his approach to the actual game design. (I.e., this exact type of disconnect between the energy/tone of this document and the energy/tone of the game is consistent with what I know of him. The self depreciation, noted in the comment below by ricardobayes, is also on brand for him.)
Source: I've worked with Chris very directly on three games and indirectly on several others. We've talked about this document in passing before (though I didn't know him until a few years later).
This might be widely inappropriate to bring up, but do you know how Chris' lawsuit against his cancellers is going? Like many players I used to look up to his work, and then was of course taken aback by the serious allegations against him; it's one of the messiest he said/she said cases I've encountered, though. Still very curious about the ultimate outcome.
