    I see what your saying, given that you remove outliers, the resulting 2 lines should be pretty similar too.

    if you remove the circled outliers the lines are quite close as you suggest.



    The risidual distribution (right hand graph) isn't really as predicted but this appears to be due to the heavy rounding of residuals before they are plotted.

    Yes, given a measure of fit. Without a given measure of fit, there is no useful meaning.
