Your Indie Film contest: short films of all genres, $5k prize

They say the films will be deleted when the contest is over. So why does the Legal section state the following:
You hereby grant to us the perpetual, unlimited, royalty-free, world wide, non-exclusive, irrevocable, transferable license (the “Licence”) in and to your Submissions. The Licence grants to Norwester, in respect of each and every of your Submissions, the rights to run, display, copy, reproduce, publish, bundle, distribute, market, create derivative works of, adapt, translate, transmit, arrange, modify, sub-license, export, merge, transfer, loan, rent, lease, assign, share, outsource, host, make available to any person or otherwise use, any information or other content you provide on or through the Website, or which is sent to us by e-mail or other correspondence, including without limitation, any ideas, concepts, inventions, know-how, techniques or any intellectual property contained therein, for any purpose whatsoever.
I get it -- they're absolving themselves from any potential legal recourse by an angry filmmaker. But why does this need to be in perpetuity? With this contract, if the parent company (Norwester, in this case) decides to start their own YouTube, they have perpetual rights to air your content. That doesn't seem right to me. Regardless, I bolded "non-exclusive" above because unlike some contests, you won't be limiting yourself (in terms of future distribution or contests) by submitting to Your Indie Film.
