What am I doing wrong with Weave here?

I’m trying to interpolate a curve that alternates between the points on these ‘arms’. The first one (with black numbers) works correctly, but the other two are wrong - they weave between the arms instead of within the arms. I’m not sure why this is happening. Appreciate any light anyone can shed.

Thanks! Any hints on why this was happening?
