I think this is a really good idea for a business you run using Bitcoin. If you have employees who don't understand how Bitcoin works, you should really tell them or teach them how to send Bitcoins as well as receive Bitcoins, so they can understand how Bitcoin works. If you don't teach your employees about Bitcoin, the business you run using Bitcoin will be in vain and everyone will be at risk of losing money.
I believe that the main reason behind that is he wants to teach his employees about bitcoin and how it will work, so I think he already taught them how to send and receive money from other people wether it is from customers or not. He should also teach them how to about being scammed and different fraudelent acts online so that his employees will not encounter this one soon, especially those thing that can lead them to online hacking or ransomware that is very harmful to his business.
