If Two-way valve (on regulator) is in between direction of arrows both bottles are open to it. If valve is in one direction and gas comes from other bottle - Turn off and have gasfitter change regulator assembly.

I have just recently changed regulator, direction valve and hoses at gas bottles, after 10 years. I thought it wouldn't hurt. I noticed a BIG improvement in performance of all gas appliances. A good move I reckon.
Keep Safe out there.

Spot on. I had issues with my gas HWS. Pilot would work but main jet wouldn't come on reliably. After a lot of stuffing around I replaced the whole regulator assembly.
The 'expert' at the specialist gas fitting shop said that regulators aught to be replaced every 5 years. It seems that they clog up with the additive that is used to provide the gas odour.
Went to change over gas bottle two way switch let gas out once it was undone
We called our friendly certified mobile Gasman when I thought maybe after 6 years of owning a 2012 built caravan, just maybe it was time for the gas system to play up.
I did notice the last time I removed the hose from the empty bottle there was a small amount of pressure which I justify as the need for the Gasman expense.
I elected not to put a new 2 way tap on or purchase 2 new hoses.
Gasman fitted 1 new hose, adjusted and serviced the 10 year old regulator, plus checked checked all the appliances.
The $200 plus, I thought was great value, peace of mind considering it was 6 years ago Gasman did almost the same work and we have about 150 nights a year in the caravan mostly unpowered relying on gas for refrigeration and cooking.
PS. My argument for 1 hose is at some point you need to disconnect that hose to change the gas bottle.
