Look, I am no expert in market laws and regulations. From what I can gather by the screenshot you have provided, this looks like it's in relation to a market participant/market maker/broker, not the actual trader (which would include the trading bot).
I don't know what you call this but this is not a wash sale, which is when you sell a security and buy it back within a very short window. That is typically done during year end window dressing when people wants to offset their gains by selling some stuff on the 30th June, before buying them back on the very next day. ATO takes a very dim view of this. Even my accountant often questions some of my year end trades to make sure they don't incur the ire of the ATO.
Anyway, back to this... not sure why the shorters would want to buy and sell to themselves - which is what you are saying?
