it doesn't look like a more advanced at all
They have more complex wallbrush and more complex autoborder.
Corner -> hook walls -> ne and sw wall (non-hookable) -> se corner but they have separate ids for: west T, north T, just se corner and full ("+" shape) so all wall ids are in use.
Same goes for mountain borders (919) - they have an id for every case of merging walls (like old solid borders). We just stack multiple ids on top of each other. Mountain borders are also highlighted in their mapeditor so we can assume that they use some kind of tool to build them.
Regarding autoborder I'm not entirely sure, but it's either like a carpet brush in RME or something that operates on spaces between tiles.
I think that this tool can also generate previews for teasers.
Can someone enlighten me on that knightmare / yurots thing?
