Issues with TileMap Terrain Logic

Question

TileSet Terrains seem to lack the functionality where tiles that lead into a perpendicular junction cannot be distinguished from tiles that merely continue in a straight line.
For example:


As opposed to:

When placing terrain, it places the latter, rather than the former, despite it meeting the former’s conditions of there being a tile of the same terrain type placed at the tile coordinates specified at the designated sides and corners.

As seen here:


The preferred tile would not have the wire leading into the perpendicular junction, and should look like so:

Based on the way Terrain painting seems to consider tiles, it appears as if it should place the tile in the latter image, since it has corner tile placement indicators painted in its corners, but it does not. Any idea as to why?

Thanks for any feedback.
