And why not? The entire ICT industry was in part made a reality by people who made their own Syntax. Besides, it's not causing any unnecessary stress on the arduino or causing any loops or anything odd to happen. It's perfectly fine.
Don't invent your own semantics for a language that already exists.
If you want to make your own language with your own semantics for the comma operator, have at it. But when you use C++, the comma operator already has a defined behavior. Familiarize yourself with it before you use it.
Just because a program compiles doesn't mean it works. Yours is not working the way you think it is.
