What about starting at 90 degrees and ending at 90 degrees?

Zero is deceptive because it is a bearing with more than one name.

Yes, 0 to 0 is zero length trignonometrically, and 90 to 90 would also be
zero length. A full circle starting at 90 would be 450 degrees endpoint.
But we don't want those complications, do we?
