On my E-Class Merc the DRLs stay lit after you lock the car. And indeed they light when you unlock it on the remote and it is dark. Isnt this the same for most cars which light when you unlock them? I realise that these inspections only apply to MY18 and newer vehicles, but right now dont even new cars do this?
It's saying "may not", meaning that on some cars the DRLs don't come on unless the engine is running and/or the handbrake is off. On my SEAT Leon they come on with the ignition, on my parents Mazda3 they don't, you have the have the engine on and the handbrake off. I think the testing advice is just trying to account for all possibilities.
