Well, in this case, that he chose those for his delimiters would lead me to believe that his data is what I might call 'vanilla' (no field contains a pipe or newline). Besides which, once he puts the data in to a RDBMS, thenhe doesn't have to worry about it.
Just out or curiosity, what do you consider good delimiters? I use '||' for field delimiters, and '@@\n" for row delimiters...
