You gotta be kidding" but I am not, the one who ordered it was ONE IMPERIAL CAPTAIN... and the only imperial authority that was near her at that moment was an inferior authority (General Tullius was too far away to hear what she said).
The Imperial soldiers were the ones who captured you, though. And everyone else brought there was supposed to be executed, so it's logical to guess you are supposed to be executed too. It's not likely they only brought you there to watch.

Ulfric had a gag on. He couldn't shout (or Shout) anything.
Besides, any Stormcloaks still there after the dragon attack would have been taken back into custody, even if they helped protect citizens. It was in his best interest to take cover and find a way out, and encourage the other Stormcloaks to do the same.
