AD8232 in two-electrode mode

I am building a wearable with the AD8232. It will have two electrodes (LA and RA). Someone mentioned they had connected RL to the same electrode as RA. Can you confirm if this is a suitable design (e.g., for grounding, noise reduction, or other purposes). They indicated they got good signal, so I wanted to check if this is recommended and if it's been tried by Analog Devices.
