I feel Luke ta a mixture of context switch and some idle time/downtime. I find walks great for letting my thoughts drift and work through things, same goes for train journeys. I think perhaps as you say, the switch unloads the information into your subconscious and then the downtime let’s it get to work.

I really liked Rich Hickeys talk on Hammock Driven Development which is basically this exact subject: load everything into your brain and then go snooze on a hammock while your mind gets to work.
