Well, note the qualifier "archosaur". It is as was already suspected - the 
wording is awkward, but they merely meant "avian" as in "not crocodilian".

It is as if you would call a hagfish fossil "human-line chordate". Which it 
would be - it would not be a human-line *craniate*, but it would not be a 
tunicate, salp etc. either.

They might have called it "the earliest known archosaur that is closer to birds 
than to crocs", but that might not have been high enough on the High-Impact 
Journal Scale of Sensationalist Sellability.
