I've looked this up. The time control in the China match and the attaching Open was G/120 with a 30 second increment. The players hated it, and John Saunders naturally blamed FIDE, writing "It really is time we all collectively got together to scream the word 'dunderheads' in the general direction of FIDE headquarters". I tried to explain to him that FIDE didn't care what time control was used, and it was entirely the organisers' decision, but got nowhere.
120 30 and the current day standard of 40/90 + 30 30 are near equivalent with the only difference that the version without the intermediate control allows the middle game to be played at a slower pace if you want to risk it. I could well imagine that players at that time were inexperienced with that move rate, as British organisers were very slow to adopt four or five hour sessions with increments, or increments in general. It's only this year that the 4NCL have adopted increments, using a six hour session to be different.
It's somewhat pointless to have a four hour session when you've got the whole day, which is presumably why the FIDE standard eventually became a five hour session. You can just about schedule two six hour sessions into a day, but it requires an early start and potential late finish.
So if you want to combine
(a) not having arbiter intervention under 10.2 or its successor
(b) a move rate slow enough to allow continued scoring and thus enabling 50 move and repetition claims
(c) a move rate fast enough to not overrun sessions excessively
I'd suspect that having 30 second increments is needed, if not necessarily from the first move.
As to what the rest of the move rate should be, that's down to what you want the total length of a game to be, presumably anything from two hours to over seven. If some events are elite, either for rating or titles, restricting the eligibility of shorter sessions is necessary unless there's a desire to allow title qualification from near rapid-play.
I wouldn't regard England as a last bastion of 90 30, rather one of the last to adopt it. I don't think we did our juniors any favours for International competitions by having all their domestic training and squad events at move rates like 30/75 + 15.
