Answer 1

According to mongodb documentation it does not support intersecting polygons. What it supports are these

1. Polygons with a Single Ring
2. Polygons with Multiple Rings
3. MultiPolygon

Kindly refer to this in case you need to know more

Answer 2

Well, yes Mongodb does not allow self-intersecting polygons. you can store them. but wont be able to perform any spatial indexing on them, or use $geointersects etc. You need to resolve the polygons first. There is a npm module for this turf-kinks
