pulley swaps are usually for supercharged applications. removing the pulley off the supercharger and replacing it with a smaller diameter one will increase boost pressure by spinning the supercharger more than the larger pulley was

I think they are swapping the stock pulleys for aftermarket underdrive pulleys. The alternator and crank pulleys that is what is meant by swapping pulleys on a N/A car

No problem, Glad I could help!
