Yes, the "automatic segmentation" of the circle to match the 16 segments of the cross is slightly different between the original and the rebuilt circle.

That has to do with some various properties of the curve like its internal parameterization, you may also see a difference depending on which loft mode you use - either "Exact" or "Refit" for profiles.

But in either case if you want to control it specifically you can split the circle up into 16 pieces and that will then control how each piece of the cross maps to each piece of the circle. If the 2 curves have the same number of segments then it will match each segment to the other instead of doing an automatic segmentation of the circle.
