Maybe not, but it is kind of implied. I think the Jedi would be smart enough to know that if there's a signal going out saying don't under any circumstances return to the Jedi temple, something real bad has happened and it would probably be best to lay low until you know what's going on.
I've never understood how anybody could think this. There must be hundreds of thousands of Jedi around at the time of the purge. It's true that the numbers have never been mentioned in any way, but it's a big galaxy and one would assume that if the Republic has stood in relative peace for 1000 years, then it would also be safe to assume the Jedi would have flourished in that time, so I think that number is sound, and maybe even very low. At any rate, to suggest every last one of them was hunted down and destroyed in less than 20 years is just laughable.
I can't imagine there would be 100,000's trained Jedi running around, maybe 10,000 but even that might be high.
