I guess this is what the theory is based on. Although it isn't exactly a roar, I can see that people could be confused, as a lion's roar, heard from far away, does have a booming quality. For all the haters: ok, so, it would be more impressive if the ostrich roared so loud that his feathers flew off. But he did his best, so cut him some slack...
This fact was discussed on QI Season 2 Episode 2. Stephen Fry made fun of David Livingstone's claim that he couldn't tell their roars apart. They played a clip of a lion roaring and another of an ostrich cheeping. That didn't make sense to me, after all, Livingstone wasn't deaf or an idiot. So I found this video. You can see the QI clip here: http://youtu.be/jUAC6qzQ4h0
National Geographic, on the 11 May 2012, made their Friday Fact on Facebook "A male ostrich can roar like a lion". Perhaps this is overstating it a bit, you be the judge.
