This no longer repros in latest:

ycqlsh> create keyspace xxx;
ycqlsh> create table xxx.t (key int primary key, value1 int, value2 int);
ycqlsh> select * from xxx.t where value1 not in (value1, value2);
SyntaxException: Invalid CQL Statement. Column references are not allowed in this context
select * from xxx.t where value1 not in (value1, value2);
                                         ^^^^^^
 (ql error -12)
ycqlsh> select * from xxx.t where value1 not in (1, 2);

 key | value1 | value2

Closing as fixed.
