It's not like that. Let's assume you have a resource Dummy1 with prefference to nodeA (score 10).If your stickiness is 20 - the resource will not fall back to nodeA (after a failure) when it returns as nodeA = 10, current node = 20 (due to stickiness. If your stickiness is '1' , while nodeA has a score of 10 - once the node joins, Dummy1 will move again to nodeA as the score will be:nodeA = 10, current node = 1 due to stickiness.
Keep in mind that for groups, all resources' score sum up before evaluation.

Unfortunately the value to set for stickiness is some what balck magic: It seems it does not make a real difference whether you set it to 5, 10, 100, or 1000; once grater than 0 it prevents resource migration, even when a placement strategy suggests that the placement is non-optimal (e.g. after a node restart).
