There is a misunderstanding here about noticing.
For efficiency reasons, the code does not check if atoms are beyond the table length.
So the code does not care about or notice anything.
However, you do care, since you do not want random forces.
(Although in nearly all cases the force will be, or zero: fine, no artifacts,
or 10^30: immediate crash of mdrun).

But what if the gmx code did notice it?

It would look up a non-random energy and force. If the code never noticed the distance was out-of-range, it won't notice it come back into range either.
