FFS, the Draenei were fleeing the Legion for 25,000 years BEFORE landing on the Orc planet. In that time, the Legion kept showing up to the planets the Draenei had landed on.

I couldn't find any source for the 200 year quote. But here is one for the Draenei being on the Orc planet for nearly 1000 years.
"I was only a dim speck of void energies when the Prophet Velen and his draenei compatriots lifted my remains and brought them here. After much ceremony, my diminished form was laid to rest within this sarcophagus. I have been regenerating for nearly a thousand years."http://www.wowpedia.org/Quest:Auchindoun...
