[2.0.72] Underground didn't remove belts if there is another belt point to it

[vinaghost]

1st line, normal behavior
2nd line, there is another belt on the south but it doesn't point to the belt line that underground going to remove
3rd line, there is another belt on the north but now it points to the belt line that underground going to remove
4th line, same with 2nd but belt is on the north
5th line, same with 3rd but belt is on the south

There is an old bug report that pantabo reported viewtopic.php?t=117656
Boskid replied but it works as I expect in 1.1.110, why changed?

I am not considering this to be a bug. Underground belts remove belts only when those belts in between are "simple" that is: they have the same direction as the underground and there are no incoming side connections. Since you have incoming side connections, those belts in between are not a candidates for removal.

Surely this is intended behaviour; seems perfectly sensible. Belts are only removed when they are in a straight line with no other interactions. This is great because it means you can just drag belts around willy-nilly without breaking already existing spaghetti.
