To be honest your line may just go a longer route. Nothing can really be done, it's never been a case of the neighbours lines guaranteed to take the same route as yours. In reality you often see a neighbours line taking a much shorter route to your own, or vice-versa.
An example is I had an attenuation of 28 and a sync around 17Mbps. My neighbour had an attenuation of 42 and a sync around 9Mbps. We were both in the master socket with no extensions. The attenuation measures line length so it was clear their line was much much longer than mine.
Simply put when lines were installed it was only a concern to get a voice signal down the lines, broadband didn't exist so there was no worry about the route taken or the length of cabling, you got what was easiest. Extremely long lines delivered voice fine so it made no odds.
Even now on new estates you still get what's easiest / cheapest vs what's shortest...
If the neighbours line goes down some ducting which was full, the you'd take another route even if it ends up much longer. Often your line goes the wrong direction to eventually do a u-turn on itself. If you're near an airport or a large park often the lines loop around the entire airport / park rather than going straight through too. It's not a fault as such it's how the networks were designed.
