But they have radar and usually extended centerlines. That should've been clearly visible for him on the screen.

Radar displays are not going to accurately display a displacement of 150m. They're set up for broader area surveillance.

Edit: here's a good example of a terminal radar display. The two parallel diagonal lines are the extended centerlines of two runways that are about 1570m apart (Athens airport, LGAV).

And that's the spacing between the runways. There is less space between the runway and the taxiway.
