Yep. All GoDaddy expired domains go to TDNAM for auction. Even those with backorders on them. TDNAM is THE place to grab GoDaddy expired domains.
They are also good at picking up other registrars dropped domains, that nobody else wants. They are also good at picking up "tasted" domains which are dropped again after 5 days.
They are hopeless at competing with other registrars for other registrars dropped domains (dropcatching). They might get lucky once in a blue moon.
Backordering domains is pretty much a waste of time ANYWHERE with the flourishing practice of auctioning off of domains before they expire/drop. The exception being domains that nobody else wants. Then you might as well register them when they become available.
