All distances are measured along the surface of the cylinder. Updated question to make this clear sorry.

I think you have misunderstood. It is a straight line in the coordinate system of the surface of the cylinder. In 3D it is a helix. I updated the question to make that clear.

comment Line intersection algorithms for lines on 2D conic surfaces.
Obvious when you think about it!! Thanks. If you write this as an answer I'll pick it as the correct one. In reality we have finite helices but this is a trivial extension.
