What is it mean by variance corrected itself to reflect higher potential variability? Kindly Explain

It means that the dataset contains more higher number than mean, In 2nd case where 5 was also 3x and 1 was also 3x, higher number would move the mean as well as variance towards itself. you can imagine these numbers plotted on a number line where mean and variance could vary according to data introduction in either direction

but in 5:26 what is written on the screen was: our sample variance has rightfully corrected upwards in order to reflect the higher potential variability, and it was pointing to the first data set, Also what is meant by mean and variance could vary according to data introduction in either direction?
