It's certainly an interesting idea.

To be fair I think that's because he has the Central line at a much
lower depth than the H&C so although it looks like it serves
Hammersmith in Map 1, that's just a quirk of a 2D representation of a
3D file.

His biggest problem is that the station "blobs" are only at "surface"
level and don't descend to the tube lines. If they did, it would be much
more clear what's going on.

I wonder whether he used actual depth information or just guessed.

He's guessed.

For example, at King's Cross the correct order is Circle, Victoria,
Piccadilly, Northern from top to bottom.

If anyone wants to try a version for themselves, you can get a good
approximation to depth information from the escalator and lift
information in CULG.

However, there are going to be problems with stations like Oxford Circus
and Baker Street where two different lines meet on the same level. I
don't see how to solve that without ruining the point of the diagram.
