I see it like when you compare digital books vs physical books: physical requires less context in your mind, and it provides direct rather than abstract stimulus to the brain.

When you go digital, your brain is writing the sticky note, but also has in its cache the instructions for the menu, the apps you normally use, that annoying notification, etc, plus your rl context. But on physical, you only have loaded the instructions for the pen and paper (and your rl context).

Having too many things in mind can reduce your executive function battery. Hope this helps! (ofc, this is an oversimplification of ADHD)
