Ultimately it is just numbers on two systems if he already has the liquid cash [1], it shouldn't matter how big the numbers are, the transaction workflow is more or less the same. In the Revlon transfer Citibank screwed up that $900M only had 3 people working on the actual execution and verification. While it is lot of one person to control individually, and even sizeable for a company to operate daily it is not that much in the grand scheme of things. These days some companies have cash balances that size, famously Apple had more than $200+ Billion in short term assets at one point. Big banks regularly deal with billions of dollars transferred around everyday. Market makers and central bankers etc do these numbers frequently without blinking twice.
