[luatex] strange behavior of zero-width box

On compiling the above code with luatex-plain,
I get a pdf in which "2" is overwritten on "3".  This is not correct, of course.

Now if I insert "\kern-52sp" (why 52sp? I don't know.)
between "1" and "\llap", that is


then "2" is correctly overwitten over "1".

I am not sure whether this problem comes from luatex engine
or from luatex-plain macro.  So I'm posting here.
