We are told that the monotony of the job makes it easy to make this
sort of mistake. *Is that because the cab windows are in the tunnel
when the train stops, and the driver can't therefore see which side the
platform is by looking through his side window?

They have to be able to see the CCTV monitors, which are at the end of
the platform by the driver.

It's also the case that the driver has spent the previous twenty seconds
*driving through* the station, and therefore the platform side is fairly
obvious.

Both of the above imply that the mistake is down to believing that the
platform is on the other side from where it is, rather than just
reaching for the wrong button.

Didn't they used to have to physically go to the window on the
platform side to be able to open the doors on that side? It's
relatively new for all door controls to be in one place, and you'd
think only safely introduced if there were protection systems in place
to compensate for the potential mistakes introduced.
