 There are a couple of notable things going on. First, ``AbsoluteValueLessThan``
 isn't calling ``process_lhs()``. Instead it skips the transformation of the
 ``lhs`` done by ``AbsoluteValue`` and uses the original ``lhs``. That is, we

 Notice also that  as both sides are used multiple times in the query the params
 need to contain ``lhs_params`` and ``rhs_params`` multiple times.
