Split Line Single Side 1

[battlehands]

I should be obtaining a total of two faces after the split line feature with "Single Side" is completed on the attached part. However, the resulting feature has three faces. Please advise.

TIA - battle

That's probably because the sphere is a single face. If you split a hemisphere, you achieve what you are expecting.

If you place the ellipse sketch on the Top Plane, you will also get what you want.
