Why isn't the counter variable reset every time the function is called?

He mentions that every time the outer function is called, a new private scope is created? What does he mean by this? Also, wouldn't the counter variable reset every time the function is called?

What creating a new private scope means is that each "innerFunction" would have its own "someCount" variable. But while the "someCount" variable is in the scope of the inner function, it's not itself a part of the inner function, so it would not get reset when the inner function is called.
