The accounting is like this. Bank A is in compliance for the current period of time under examination (capital requirments and reserve requirements). Bank A makes a loan L1 to person B. This is a contract. Bank A has an asset in L1 on its balance sheet(this improves its capital ratio) and person B has L1 on her balance sheet as a liability. Person B makes a deposit of L1 amount into Bank B. Bank B has a liability of L1. Person B has an asset of L1 which is her deposit which she owns. Finally, Bank A makes a reserve payment to Bank B of L1. These reserves come out of the reserve account that each bank has at the Fed. The reserves maybe borrowed in the Federal Funds market on demand so long as the bank is in compliance.
