A couple of guesses spring to mind.

1. Left over debugging code, when an error occurs then being able to 
look at the buffer would be quite useful. It was either left in by 
accident, or because changing it was deemed too dangerous.

2. A workround for another bug which may have been fixed & the workround 
left in, or it might be less serious than save@ and nobody noticed.
