1) Why the need for 4 A1 route relations?
I'll leave that to others, but
2) Why the need for even one? After all, the "ref" tag on all the component parts of the A1 should identify them without the need for a relation.
True. A relation should only be needed if a stretch of road is shared by several numbered routes (don't know if that happens at all in the UK). However, because the availability of services that can quickly respond to a query like "give me everything tagged ref=A1 in the UK" is patchy, people tend to create relations as easy access handles - once you have such a relation, you can simply get /api/0.6/relation/12345/full and you have the complete A1 from London to Edinburgh. And possibly back again.
