I don't understand the difference in this context. The parent gave a few examples of how the Olympic venues in London have been repurposed for long-term use, so... Are you referring to financial sustainability? The sustainability of the Olympic model? What exactly?

I'm guessing it's a reference to the TV show Twenty Twelve, see https://www.youtube.com/watch?v=BYbA2Xsu6VE

He may be referring to the fact that the city rent out the Olympic stadium in London at a very low price to a club who can't fill it and which requires a lot of policing costs. West ham were given the lease do that the stadium wouldn't stand idle.
