I filed an issue now. I took a quick look earlier, but didn't find where the problem originates from.

That's a known issue and hard to avoid.

Yes and no. The instructions are associated with maneuver points, but the system mainly works by comparing the GPS position with the route polyline segments, finding the closest segment and then the next maneuver node following that segment. Additionally, there are some tweaks to account for positioning inaccuracy etc.
