Yes, that's right.I believe they meant 4 signalling blocks/berths (well, 4 for each of the two tracks).
I'm not confused about the layout; I know it quite well. It's just understanding how exactly the two maps overlap.
Yes you are right. I should have been looking more carefully. I see now that this means that the 4 blocks shown on the other map have to be located prior to that junction.Lewisham Vale Junction - where the top lines leave your first image - is at the bottom left of your second image, and clearly labelled.
And from watching the maps more closely, I think that the last block of the 4 on the first map, is the same one as the one shown just below Lewisham Vale Jn on the second map. So that is where the overlap occurs.
I think for some reason trains often don't appear in that overlap block at all; they sometimes seem to skip it, and that is probably what has prompted my confusion.
