Actually, drawing a curve though points will not be exactly the same as the 2 joined curves. there can be huge differences. Because points are assigned varying weights, depending on what type of curve being drawn, and depending on it's proximity to the end of a curve. When you draw a new curve through points, the new points are not weighted in the same manner. and Moi has no system for adjusting point weights... so you will always have to decide what is an acceptable deviation for your model when joining and deleting a point, no matter how you attempt to clean it up...
