In (2), if you are searching for points on R1 then you can be sure
that they lie on R1!

However, if a route A to B passes through C, D and E in that order --
that is, Google finds the route A-B goes A-C-D-E-B -- then you can be
reasonably sure that it has found the optimal route. So the route C-E
will also pass through D, and D-E will follow the same roads as that
part of the route A-B.

The directions service uses the geocoder to find start and end points,
so you can use anything the geocoder recognises. That's generally
addresses and not businesses; in some countries milestones or
junctions might work.
