Right.

No there isnt a new node S after cutting.

After cutting the tiles look like this:

Tile 1

  A-------------B

Tile 2
                C
                |
                B
                |
                |
                D

The boundary node is now B. Its apperas in both tiles.

So I think it could be ok with B tagged as boundary node in both tiles.

I use a own tile splitter.
