All done!

It depends.

When someone diets, they have a calorie restriction to lose weight. When the goal is reached, they should relax the restriction so they stop losing weight and add calories to maintain their goal weight. Do we consider the new calorie level still a "diet?" I don't know.

Social distancing can be the similar if the behaviors to flatten the curve initially are like a severe calorie restriction, then when we reached the goal (what ever that is), we can "add more calories."

So the goal of social distancing and curve flattening needs to be defined. The problem I see, is that it went from "preventing local healthcare resources from being overloaded" to "reduce cases to zero" by some standards.
