I don't think you understand the problem.

If you push a packet along the shortest path form node to node it will stay on 
the path. Because the shortest path on the next hop is still the same path you 
calculated on your node.

But when you want to move traffic on the "second shortest path" (as an 
example) the next node a will route it differently, because "second shortest 
path might not be the same for this node (even if you mark your package so the 
next hop will know that this is "second shortest path" traffic).
