[texhax] Odd behavior in a \mathop

If you compile the file
\newcommand\II{\mathop{I\mkern-1mu I}}


$AB\I L$


you will see (or I do anyway) that the I in the second, but not the first, 
formula is going distinctly below the line.  What is going on here?  If 
you take out the \mathop this does not happen.
