iMessage sometimes not received, when messages in Mac is active and iphone is not

Hi,

Lately i didn't receive some messages only later to find them in my Mac's Messages application.

What i understand from this, is that if my iPhone suffers from temporary disconnectivity then the iMessage is still routed to the Mac,

but will never be pulled by the iphone .

If that is the case then when i am in an elevator or out of power , then the iMessage center

knows i have iMessage "on and active" and it will send it to my Mac and the iPhone will never be notified.

Correct?

Thanks
