The vertices of one line can only have the value 1 or 2. (Don’t ask me, why the vertices numbering does not start from 0 … :-) ) The vertices are numbered  according to their order of creation. To find out the order of their creation (If you have a lot of lines, you cannot remember which vertex you have created first), you just have to move the cursor of your mouse above the two vertices of one line, see following figure.
