The loop maneuver used by buses to go to the charging point is visible on the Transport Layer.  But be assured that it is tagged correctly.  The service stop has "access=no" and this small loop relation also has "access=no", so it will not be offered as a regular service to people using OSM-based apps.

We need such relations to have a full coverage of bus itineraries, because it serves to measure distances, identify roads that would impact buses if they are closed, and much more.

Again, thanks for raising the question, it is always interesting and once in a while we can find real mistakes with this approach.  But not here. 😉
