Why seperate pins for Max485 De and Re #2

Could you explain to me why you are using 2 pins on the nodemcu to drive DE and RE on the max485.?
In the program they are both held high or low together so why not just tie them together?

You can tie them together, it's normal practice to do so [as I have done], as is also having them separately connected.

This really isn't an issue, you should close this issue.
