It's not. Having the light source - in this case infra-red - beside the
lens means it reflects straight back into the lens.

If the IR illumination and camera were perpendicular to the number plate
I would agree, but that would be unlikely. The only other issue is with
snow/rain/fog where there is significant local reflection.

Car number plates reflect light from more than one direction.
