Why this total residual error shows 0.5?

I confirm the function 'findchangepts' following code.
findchangepts([0 1 2],'MinThreshold',0.5)
this result shows total residual error = 0.5. But, in my understanding, each points of residual error are 0, -0.5, +0.5, so the total residual error is 0. Because the values of residual error is each points to red line.
Could you explain me why this total residual value is 0.5?

Hi Kazuki,
Hence, in this case, 0^2 + (+0.5)^2 + (-0.5)^2 = 0.5.
HTH.
