This is a feature not a bug.

If one of the words is slightly wrong, then you want it to be obvious.

If the Kentucky emergency operator adds an extra s they will see that it can’t be right. With the contiguous numbering the ambulance would be close, but probably still unable to find you.

OK. But you need the W3W API to do that. Just by looking at two identifiers, without that, you'd have no clue about where they are.
