Bridges “cut” if and only if they have exactly one common point that is not an end point. what does this line mean…does it mean that 2 bridges can end at same point…

But tell me one thing …it is said that they are discovering the points .then tell me how can they discover same point 2 times…
see they just want to tell u if bridges intersect at the end point then dont consider them as intersecting (check left arrow example).
check right arrow (it is a valid example of cut)
