Unfortunately the one I tested starts at page 1, (stamped page 4) and I can't move back from there, which is presumably where the extra information is. These are rural areas with groups of villages in one book, probably done by several enumerators. Perhaps I hit on a bad one to test, as I have sometimes come across extra pages, though not routes, which are sometimes fairly random, as far as I can follow them.
Villages did not have addresses, even in 1911, many just give their address as the village name, or at best "the Street"!
