Walter has posted HC rule 154 which shows it is legal.
If vehicles are close together, one will generally have proceeded over
the first white line at the time the signal turns red.


Only if the driver ignores the meaning of an amber traffic light.

Nope. If the vehicles are close enough, one of them will have to wait
between the different Stop Lines, in order to obey the HC and the law. And
vehicles approaching traffic lights in London are often close enough to
stop a Taxi pulling into the gap.

So you are talking about the case where a car is in a queue moving slowly
forward. The traffic lights change from green after he has passed the first
stop line and before he has passed the second line. TSRGD2002 Section 5
paragraph 43 says,

'2) Where the road marking shown in diagram 1001.2 has been placed in
conjunction with light signals, "stop line" in relation to those light
signals means -


(a) the first stop line, in the case of a vehicle (other than a pedal
cycle proceeding in the cycle lane) which has not proceeded beyond that
line; or

(b) the second stop line, in the case of a vehicle which has proceeded
beyond the first stop line or of a pedal cycle proceeding in the cycle
lane.'
The road marking in the diagram is a stop line incidentally.
However, red light cameras are not normally activated until a few seconds
after the lights have turned red and they take two photos a short time apart
to show that the vehicle was moving after the red light came on. If a car
stopped at a red light inside the cycle box he hasn't committed an offence
unless he entered the box whilst the red light was on. In which case he
would have passed the first stop line a few seconds after the traffic lights
went red.
