Confusing the value NULL for a non-null string-sequence which says “NULL” shows the clear sign of a system where no data can be assumed to hold any integrity.
These bugs and categories of errors should simply not be possible in sane languages or frameworks.
That's not what's happening at all please reread.

So it's 'confusing' the string NULL used incorrectly (kind of, it's fine under the assumption that no one will have the license plate NULL but that assumption is wrong) with the string NULL.
