I assume the source address was spoofed, but this leads to my question. Since the person that submitted the report didn't mention a high packet rate (it was on ssh port 22), it doesn't look like some sort of SYN attack, but any OS fingerprinting or doorknob twisting wouldn't be useful from the attacker if the traffic doesn't return to them, so what gives?
Highly-distributed, pseudo-randomly spoofed SYN-flood happened to momentarily use one of your addresses as a source. pps/source will be relatively low, whilst aggregate at the target will be relatively high.
Another very real possibility is that the person or thing which sent you the abuse email doesn't know what he's/it's talking about.
