I believe it can work some cases.
One of those cases would be if one side was being too clingy and pushy or if he/she suddenly stopped communicating with you.
Ultimately with this you are just playing games and not being honest at all.
If you did something wrong or really want to reach out to the perosn you love then do it and if that person doesn't want the same you do then you should move on.

In my experience the "no contact" rule is more for when you want to move on. Sometimes it will cause an ex to become interested enough to contact you again. Usually though it seems that the ex's contact you again after a period of "no contact" to pretend to be friendly and try to get a booty call after x amount of time. I've never had it work out that it got us back together in a relationship.
