Does "Zero Fees" on SWIFT deposits mean that Binance absorbs the SWIFT fee or just that there is no additional fee?

The SWIFT system itself has a fee that depends on the bank, but at the same time, this is on the Binance FAQ:

Deposits will need to be made in USD via SWIFT transfer to Binance’s bank account in the U.S. and your Binance account will be credited with BUSD at a 1:1 ratio. For each transaction, the deposit and withdrawal transaction fees are US$0 (waived) and US$15 respectively.

​

So does that imply that Binance subsidizes that fee or am I misunderstanding something?
