Explanation: A possible example for discussion:
The boys bought themselves lunch.
In this sentence, <em>themselves </em>is the indirect object (reflecting the subject) and it serves to mean that the boys bought their own lunch, So reflexive "as-is." If the word is moved to another position in the sentence, it could be intensive.
