Doesn't matter. You want to know why? Because most backoffs don't happen at the table unless you're alone there or they simply have no choice (a threat) and simply don't care about any possible backlash or questioning from the other players or they determine that the other players won't care. So to avoid this they'll get you instead as you're leaving, coming out of the bathroom, or if you mistakenly go to the cashier(where most backoffs happen cause of the great camera footage there). If they can't get you as you're leaving, expect the tap before you even place a bet the next time you come in as they'll have you photographed and on alert for your next visit.
All of this is irrelevant anyway because casinos are powerless to trespass you. So who cares if they back you off, just give it some time and come back again time and time again. Casinos are not the private property they like to claim to be. While they're a private business, they are bound by public laws since they are a public place. It's simply unconstitutional for them to trespass you without good cause. Now if you're causing a disturbance, destroying property, that is different and they'll have legal grounds to prevent you from entering the building again and if you come back you'll be arrested.
Go ahead and find me one card counter who did nothing malicious, wasn't disorderly, caused no trouble, and simply played the game like everyone else and ended up getting arrested and convicted of a criminal trespass in court and you'll have your answer. And that's IF they even get arrested because most casinos are not stupid enough(surprisingly I know) to put cuffs on you. So even IF you do get arrested, it will just be thrown out in district court once you seek discovery. You don't even need a corrupt lawyer either. Use your 6th amendment rights and represent yourself and save the expense.
