That is because sketch4 is not going in the same direction as your other 2nd direction sketch. I think the solution you want is attached. I used a sketch point on a plane normal to the end of the bowl as the 1st direction, 1st sketch then sketch4 then Sketch2. For the second direction I used the selection manager to pick the elliptical sketch curves in sequence.
I'm a little lost by your description. I kind of understand and am trying to follow it through.
You couldn't step by step it could you?
