The way the meshing process works is it starts with quads generated in the UV space of each surface and then the quads are turned into n-gons where there are trimming boundaries.

Currently the goal of the mesher isn't really to produce the same output as you would when drawing something by hand with "all quads", it's goal is to automatically generate a render-ready mesh with a good looking lightweight wireframe.

If you don't want n-gons you can change the setting "Output: n-gons" to "Output: Quads & Triangles" instead, then those areas will get triangulated instead.

In the future I do want to try and make an "all quads" type mesher, but it will require a totally different approach than the current engine.
