I'm reading the tutorials and got problems understanding the start
and end
of a link
.
For example, here are 3 links between hs1 and /hs[2-4]/
ID start end ID start end
hs1 100 200 hs2 250 300
hs1 400 550 hs3 500 750
hs1 600 800 hs4 150 350
To my understanding that only two points are needed for a link. Just couldn't understand why 4 points are needed here. And the docs says only the start and end of the link as well as some other tutorials online.
