Position of 1st leg track is also moved when moving 2nd leg track after rotating 90°

[Gordon-Dry]

Example:

Going 0° alongside the edge of a field, rotating 90° to direction 90° at the corner, altering the track to settle it fit for this 2nd leg, proceeding, at next corner just rotating right 90° to direction 180°, not altering the track, believing it's already set on the 1st leg.
Same at next corner, just rotating right 90° to direction 270°, because the track was already set at the 2nd leg.
Now comes the issue; at the last corner after rotating right 90° to direction 0° the track is offset.

As it seems the track is offset the same amount I offset the track on the 2nd leg.

I believed the legs 1 and 3 for 0° and 180° have a different "track setup" as the legs 2 and 4 for 90° and 270° as my intuition told me as it should be like that.

Please fix that behaviour to be such intuitive.
