A ratite-like system seems to make a lot of sense for non-avian theropods, so 
it isn't such a surprise. 
It's good to see some evidence of it though.

I myself once postulated that the Lark Quarry prints here in Australia might 
represent a single large 
theropod taking a creche of young juveniles down to a lake to drink, rather 
than a lone predator 
spooking a group of smaller theropods of a different species. The fact that 
some of the smaller 
theropod tracks are inside some of the larger ones might suggest they were 
following close at dad's
