The diagram proves nothing: the two loading tracks converge onto a single departure track, which won't be signalled for 90 s headways, and as soon as the corner is turned at Lidcombe, no track to the city is signalled for 90 s headways, otherwise Sydney would have had vastly better services for decades.
The slower loading is a management myth: the loss of time for slower loading is more than balanced by the total passengers per hour per track. At normal specified performance, and with speed-proving approach signalling (as installed at Circular Quay in 1955, and as used on Paris RER line A), there are 80 s available for boarding with 120 s headways, and I have never measured a Sydney set go beyond 70 s.
2000 passengers on 30 tph = 60 000 per hour.
1200 passengers on 40 tph = 48 000 per hour.
Sao Paulo metro tried for 90 s headways, and didn't succeed.
