Please help me understand why this is a "more ambiguous" case.
To me, alternative interpretations have extremely low scores for
utility and likelihood:
(1) 'and' has higher precedence than 'in':
'one' in (f and 'two') in f # chained (x in y in z)
(2) 'and' has same precedence as 'in':
(('one' in f) and 'two') in f
