3.6v sbslider is not too low, that is the nominal voltage , also a good storage voltage(maybe 40-50% capacity. Most cells (variable) have a min voltage of 2.5-2.8v, so to play it a little safer, 3v minimum is a safe voltage to not go bellow(leaves a little room). But even then, if the voltage is bellow the min spec, for example it is 2.3v measured. As long as the cell has not been in this state for a period of time, it should charge up fine(being monitored to add) with minimal issue/potential damage. Most lights do have a built in LVP, also even without the LVP(low voltage protection) not many flashlights will power up at 3v, or certainly not in high modes. As with the load and voltage sag, it will blink or go out letting you know.
The little RCR123a cells(16340) do not have much capacity, usually 6-700mah in the tank(yours is 550mah ). Its a good idea to use the light and check cell voltage after a few uses. This way you will get an idea of how much use and where the voltage will roughly be. With my 16340 cells, i tend to top off back to 4.2v after use, as even a little use with higher levels(exl low and moon modes) does eat through the mah pretty quick. So by topping them back up to 4.2v, i know exactly where i am up to and good to go again. Now at 3.6v, you dont have that much left, certainly if your going to be attempting higher levels(if the light allow use at that V). If its for regular use, i would certainly carry a spare cell or 2 for the light. If you find your swapping cells out regular, then a compact 18650 light may work better for you. I love 16340 lights, the form for me is perfect for EDC uses, but not ideal for any decent duration. I would struggle in work for example, where a few hours of 200lm( ish as a variable) might be needed.
3.6v is a good place to top back up yes, but there are no safety issues at that voltage, nor going lower towards 3v. Maybe he was just giving you a large buffer to be extra safe, but i am sure the olight mentioned will not work bellow 3v.
