Why is O'Sullivan always sitting on the left side?

I had a look at the sessions from the 17 days of the Snooker World Championship in 2020 to see if the theory that the higher seeded player is seated by the yellow pocket side. This seems to be the case and the highest seeded players score will also be shown on the left side on the screen as well.

In a two table setup the highest ranking player will still sit on the left side but in the same corner. I have also noticed that the lowest seeded player will be announced to the table before the other.
