Ya, I forgot to mention this deficiency - multiple touchscreens of the same
type won't work with this simple proof-of-concept script. To handle this
case, there could be a tool that pops up a full screen message overlay on
one touch screen display that says "Touch this screen". When there are N
displays of the same type you'd have to do this N-1 times. To launch this
tool, a desktop notification could pop up upon logging whenever N-1 > 0:

Touchscreen configuration is incomplete.
[Configure now]

Or... an alternative approach could be the first time a touchscreen display
is touched that has an ambiguous configuration, popup dialog that says:

Which display did you just touch?

And the user could respond via key press or mouse click.
