Or the words he retains indicate what he has omitted.
Sometimes the quoted portion itself points to the missing qualification so clearly that the omitted meaning is not concealed. Such indication may justify a carefully limited abbreviation. Yet a vague possibility is not the same as meaningful and identifiable indication.
For example, keeping the words “once that condition has been satisfied” makes it apparent that a claim is conditional, although one may still need surrounding context to know which condition is meant. Investigators ask whether the actual quotation conveys the required meaning, rather than supplying it through unverified guesswork.
