The question is rather specific and can't be answered without analyzing the LM101 internal circuit. You'll find it in the datasheet.
Your circuit differs from the clamping options suggested in the datasheet and I wonder if it is effective at all. LM101 isn't designed as a comparator, maybe the diode is sligthly speeding up the response.
As in most electronic circuits, you'll find that there are boundless possibilities to achieve a specific purpose. It's often easier to design your own solution than analyzing an existing circuit exhaustively.
