This is normal behavior.

Once you move "to", the vertex is moved to the "ref point". When you then try to move "away", and the vertex is already at the ref point, it doesn't really know which way to move (the script doesn't remember the previous location of the selection).

Think of it as drawing a line from the "ref point" through a vertex you want to move. For example, if the ref point is 0,0,0, and the vertex we've selected is at 1,0,0, then our line would start at 0,0,0 and point along the positive X axis to 1,0,0. All "toward" or "away" operations on that vertex would slide it along this imaginary line. "Toward" would move it along the negative X axis, and "away" would move it along the positive axis.

However, if both the ref point and the vertex are at, say, 1,0,0, then "toward" and "away" become meaningless --- our imaginary line from the ref point through the vertex is a zero-length line with no direction, as the line starts at 1,0,0 and ends at 1,0,0.

Hope that makes sense.

If the vertices are in the same object, then you're right - it becomes difficult to know which vertex you're selecting. At this point you simply have to single click the 2 vertices and only one will be selected --- which one is selected, of course, is anybody's guess...
