You can't just lockdown and then stop, unless you eradicate the virus entirely, which is impossible. It only stops in the absence of lockdown when the herd immunity threshold is reached. Period. The only question is what that threshold is. Without these findings of heterogenous susceptibility, that threshold would be 70-90% depending on your estimate of the effective reproduction number. With these findings, that number drops to a much lower threshold. Much, much lower. -- If I can ask you one question, what is your explanation as to how cases have floored in other first-world countries, in the absence of herd immunity, if they are not practicing lockdown?
