My kids are autistic and so I have some sympathy with parents of kids who have to do things a certain way or else face a meltdown. It is really a hard way to try and navigate life.
That said, we taught our kids that if they wanted to press the button, they had to be fast AND everyone else in the elevator got to press their own floor unless they asked our kid to press for them. We taught them to ask others "what number do you need?" Most people are gracious and allow a kid who asks that to press the button.
In this situation, I would have asked the kid "can you press number 4?" If he didn't do it within like 5-10 seconds max, I'd reach over and say "okay, I'll do it instead."
