+    When a multiple key conflict happens in a REPLACE command mysql
+    expects the conflicts to be reported in the ascending order of
+    key names.
+
+    For e.g.
+
+    CREATE TABLE t1 (a INT, UNIQUE (a), b INT NOT NULL, UNIQUE (b), c INT NOT
+                     NULL, INDEX(c));
+
+    REPLACE INTO t1 VALUES (1,1,1),(2,2,2),(2,1,3);
+
+    MySQL expects the conflict with 'a' to be reported before the conflict with
+    'b'.
+
+    If the underlying storage engine does not report the conflicting keys in
+    ascending order, it causes unexpected errors when the REPLACE command is
+    executed.
+
+    This flag helps the underlying SE to inform the server that the keys are not
+    ordered.
