Hi Dragan,
Internally all splines are being converted into poly-lines (composed by straight segments) and this causes that positions and tangents along the spline are not "continuous", but discrete values with these small differences. You would need to add short straight lines to the both sides of the arc to make these parts perfectly aligned. For example, the Sweep modifier has the same problem. I hope that clears it up.
Best regards,
