Visibility strobes.

I couldn't see any navigation lights.

Not necessarily on during daylight.

What might that have been doing?

Waiting at a holding point for permission to join the landing circuit.

If it was that you'd expect that he would have seen
that before

That depends upon the type of airport, the type and size of aircraft and
how busy it gets. Most of the holding points for my local airfield are
rarely used because it rarely gets that busy.

and they don't do that in very tight circles.

Depends on the size of the aircraft. I used to in mine.
