My response from Sky:
"Thank you for contacting Sky Sport Now Support.
These new features are based on user feedback, to make your viewing experience with Sky Sport Now even better.
On Demand will be available more quickly – as we shift from being able to rewind from up to 24 hours to up to 6 hours on live channels. To make sure you can watch events shortly after they’ve finished, we’ll be getting more On Demand replays and highlights in the hours after an event has finished so you can watch when it suits.
Please let us know if you require any additional assistance. "
I've gone back and asked whether that means they're committing to making the content available within 6 hours, but I doubt that will be the case.
