I don't think he did his research terribly well .
There are many variations on the general structure of the Swiss tournament, but the key idea is that the first few rounds are randomly paired, and the remaining rounds are power-matched.
That view was obsolete fifty years ago when Stewart Reuben and others devised any number of deterministic systems for making pairings based on the rankings of players.
What they didn't do was follow up on a system devised for the British Championship whereby they ranked the top half of the draw in the first round, but randomly assigned their opponents from the second half. That was how, for example, in 1970, the defending champion got a pairing against the future 1972 champion and lost.
It's a necessity that pairings can be reproduced to avoid accusations of bias. Given the existence of pseudo-random numbers, that condition could still apply even where pairings were partly determined by lot.
Given the discrepancies between rankings determined by ECF grades and those by FIDE rating, arguably a tournament using FIDE ranking orders has already been partially randomised.
