No sorry, after renaming this will be:

(assume rhs_2 (not rhs_1))
(assume lhs_2 (and lhs_1 rhs_2))

or if we prefer from an real dump:

(assume #(mvar 22593374 2 (not (integer 3 3))) (not #(mvar 22590962 2 (integer 3 3))))
(assume #(mvar 22593448 0 (or marker number)) (and #(mvar 22591258 0 (or marker number)) #(mvar 22593374 2 (not (integer 3 3)))))

Sorry my development time budget for this week has been almost entirely
consumed now, I'll try to come back on your many mails but I have other
duties in line.

  Andrea
