Android can delay notifications for power saving reasons. As I understand it the more there are from one app and the less the user interacts with them, the more likely they are to be delayed.
I think to do what you want more reliably you'd need to use background processing (wake up every 30 seconds, clear the current notification and replace with a new one) and I don't think LiveCode enables you to that yet.
