It's very poor mapping to assume aerial imagery is current.

If I'm judging the angles correctly, OsmAnd will not even announce that
intersection: the angle between Wapping and Commercial is shallow
enough that OsmAnd sees it as a single road, while the angle between
Wapping and the roundabout is sharp enough to not require a "keep
left" instruction.

If two ways enter a roundabout at the same point, you can turn from
road A into road B instantly,
but going from B to A will require going around the entire roundabout.

It doesn't work like that anywhere in OSM. I can cross a road that I'm
not allowed to drive on. The router does not need to know anything
about the road that I'm crossing and I can always cross a road that
I'm not allowed to enter.
It would make mapping extremely awkward if that were not so.

Technically speaking you are not because you are just touching one

Yes you are. You may not be on there very long, but you approach the
