Yes, it's completely 100% standard practice as other replies already mentioned. What's funny is that the tone of your question suggests he's doing something fraudulent. If you were the company auditor or a government prosecutor, and you didn't know about the standard practice or simply wanted to be a jerk, you could absolutely make a case for fraud. If you were fired or prosecuted for keeping the miles, what would be your counterargument? Everyone else was doing it? That doesn't work for speeding tickets. This is an example of how arbitrary laws can be.
