1) If a route with only few waypoint is rerouted by another app, the way between the waypoints is determined by the 2nd app. Of course the 2nd app can decide to go another way. E.g. if it calculates for cars instead of walking.
2)
For a track with thoundreds of waypoints it makes not much sense to export a route. For a manually created route (not following a road, but straight lines) with max. some dozend WPs I would just go the other way and create a route in full xml format and even add the routepoint names (or at least the numbers of the triangles). See the example below.
Advantage of this format: If you export it to e.g. Garmin, the device can show you the WP names and you can route accordingly.
[Yes I know XML has some redundancy but there are sufficient reasons, so it succeeded in getting the standard in computer programming.]
