Maybe this is because of the motor_vehicle=permit tag: https://www.openstreetmap.org/way/30952472

Since 1931 private car traffic isn't allowed in/to Zermatt. There is a special permit which is only issued to locals, some guests and for supply/rescue.

I didn't check what OsmAnd is exactly doing but your description doesn't sound too wrong. OsmAnd could ask if you have this special permit when trying to calculate a route. And ideally it shouldn't just show a straight line from the end of the route to the final destination. This can be very misleading. Maybe present a notification to the user that the last n km of the route couldn't be calculated for the current transport mode.

While checking, I found that the route from Bern to Zermatt 4 on Google Maps matches the route created by our web version. You can view it here: Web version link.
