Yeah, that could be, but there is also another possibility that it's showing you something more like a history of the curve with the original points that were interpolated to draw it (it only has a "through points" draw method, is that correct?) . If that's the case then editing a point is not actually so much editing the curve but rather creating a brand new "through points" curve using those points - creating a whole new curve like that is slightly different than actual curve modification methods.

Do the "points on the curve" show up for curves that you've imported from other programs or only on ones created inside of Solid Edge?

Or it could be a kind of hybrid - showing knot locations for imported curves where the construction history was not known, and showing points to interpolate for curves that were drawn right in SE...
