They replied my email. Given that I'm travelling from Chur to Brig, the bottom seats are the left side(what I selected on and took a screenshot and sent to them).
Here is the reply:
"At the moment you are on the left side. But as our trains and wagons can be changed it is never guaranteed that you are on this side.
The Glacier Express is running with panoramic wagons with huge windows. You have a wonderfull view from every seat.
We thank you for your booking and wish you a wonderfull journey."
