Although the sentence means that he is the most generous of all, I don't think we should necessarily take this sentence literally. You may say so to emphasize that someone is extremely or unusually generous just as the idiom goes "He is one of a million".
The use of "couldn't" with a comparative degree of an adj is quite interesting here. It indicates the meaning in the present, not in the past. According to McMillan, we do so for emphasizing that someone or someone is extremely good or bad. Here, in the sentence, it means he is extremely generous.
