Create anchor points at intersecting paths using combine shapes
When I'm using the path tool and I use the combine shapes option I've gotten 3 different results and none of them are consistent.
Most of the time my overlapping shapes look like this.

Though some times it ends up like this.

But every once in awhile I get overlapping paths with extra anchor points where my arrows are pointing, like this.

This is my desired result but unfortunately it doesn't happen all the time and sometimes I can't make it happen at all... what am I doing wrong?
