So it clearly explains that an INDEX...FOR (Filtered Index) can be optimizable if the expression is optimizable.
But, if have this set of commands:
SELECT y
SET ORDER TO code (INDEX ON code TAG code FOR code = 'I' - an optimizable index)
CALCU SUM blah..blah.. && not optimizable anymore
SCAN FOR.... && not optimizable anymore
