In the Stablecoin Scanner's methodology (working definition), exchange netflow is the net of stablecoin inflow and outflow across the boundary of an exchange's address set over a window. A transfer from outside into any of the exchange's addresses is inflow, one out of any is outflow, and a deposit swept into a hot wallet is internal, so a customer deposit counts once. The scanner reports figures per window with the days actually measured, and calls exchange balances a floor of on-chain stablecoins, not reserves.
