Deleting converation from Messages doesn't delete it on iOS?

[micrors4racer]

When I delete a conversation on messages on my mac or my iOS devices it does not delete it on the others. Is this feature not implemented yet?

I haven't seen anything about it supposed to do that. Been using 10.8.2 as well and everything with iMessage and unifying my phone number with my Apple ID (using iOS 6 beta 4 on my iPhone 4s) has been working fine. If anyone else wants to chime in and provide any other insight, feel free.
