I'm pretty sure the above features are because much of the signalling is
bidirectional. Something said in uk.railway a while ago reported that the
aspects displayed for the wrong direction movements don't just show
permanent reds until a train happens along.

Stop signals for wrong direction movements *will* show red until the route
is set for a train running the wrong way.

However, these sound like repeater signals that can't show red. This often
happens on reversible sections.

Thanks for the clarification Clive.

I should probably have written '... don't just ALL show permanent reds...
