bent torus sometimes has seam, depending on dimensions -- mysterious

I'm trying to model O-rings wrapped around cylinders. Some sizes end up with a seam. Does anyone know why?

For example, this one is fine:



but this one has discontinuous surfaces:

I thought perhaps sometimes the sweep can't follow the path without the profile "kinking". But in the example shown, the continuous example curves more sharply than the seamed one. I'm baffled.

Here's a test document:


If you can shed light on this mystery -- or even better, suggest a way to prevent the seam, I'd be grateful.

Cheers!

Jim
