Hi andras, yes you get edges in separate pieces in that case because your cutting curve is not just one single piece, it is actually a curve made up of 2 segments.

If you select that cutting curve and run Edit/Separate on it, you can then select the segments individually to see that.

So for example after running Edit/Separate you can see this:



I think that Burr has got a good solution for you above - use the new Merge command in v2 (which you need to either type in or set up on a keyboard shortcut to run it). You can either select the whole object, or just those 2 edges (hide the original cutting curve to get it out of the way) and then when you run Merge it will fuse those 2 edges together into one single longer edge.

Please let me know if that still does not solve your problem.
