The pronoun's only possible referent is the \"two or more options\"; as stated, you choose one or more of those options, in any order. Nothing suggests allowing an option to be chosen repeatedly. (And as @fantasai implies, its placement in the \"combinators\" section rather than \"multipliers\" also further suggests that it doesn't allow multiplying a single option.)"}}
