sharking or otherwise
I tend to agree with what everybody's said so far. First, if he seems to be unscrewing his cue, he's unscrewing his cue, and it's a concession. Second, once the referee makes the call, the call is made, and the rack is over. Third, the rack should've been continued rather than re-racked, especially with two easy shots to go.
On th'other hand, I know a lot of players who fidget, especially with their cues, usually not in front of the player shooting. That's the real question I have on this one. Was the opponent visible to the shooter when he made the unscrewing motion? It's not sharking if you can't see it.
Frequently when i'm heading back to the table, I unseat and reseat the pin in my cue so I can be sure it's rock solid before I stroke. Obviously if i'm doing it on my shot I'm not conceding that way, but I have to be sure to keep the cue out of my hands when i'm not shooting because it's become a nervous tic as well as pre-run routine. I say pre-run rather than pre-shot because I don't do it between shots, just before the first shot back at the table.
