For a car, TSGRD2002 43(2)(b) defines "stop line" as being the first stop
line, or, if you've passed it, the second stop line. So, if you can's stop
safely before the first line, but you can stop safely before the second,
that is what you must do.

That is how I see it too.

If you increase your speed before crossing the first line, so that you
are not then able to stop (safely) before crossing the second line, you
will still be able to obey that rule whilst passing both lines on amber.

The same can be said about a traffic light with a single stop line. In
either event, you risk inviting the attention of the local constabulary,
who might fancy a little chat about your driving.
