P0155#10 confusing answers

Question

Avensis 2.o pet 2001, (Asian), showing code p0155#10, bank 2 sensor 1 heated O2 sensor.
I was told bank 1 is cyl 1 etc, sensor 1 pre cat, 2=post cat. However this thread;

https://www.autocodes.com/qa/8785/bank-sensor-right-looking-from-under-bonnet-avensis-vvti-2002

suggests I'm wrong unless car is LHD. I believe I'm looking for pre cat sensor for cyls 3+4.

Also showing code #10 but data tables show this has no meaning.
