For award tickets I think the same is true, so I would suspect if you book a flight today for travel tomorrow that it would be subject to redeposit fees.
United, as far as I know, never pays attention to 7 day limit. I've purchased and cancelled within 24 hours of traveling for free on a fare that had a cancellation fee.
{edit to clarify I dind't pay a cancellation fee!}
