The update is not occurring because your WHERE clause is returning a false.
The result, step by step:
Step 1 WHERE X = :IN_x <--- TRUE > AND (Y <> :IN_y OR <---- FALSE > Z <> :IN_Z) <--- Unknown Step 2 WHERE TRUE AND Unknown <--- FALSE
with an AND condition, both sides of the AND must be TRUE and here, they are not. So, the update does not take place.
