It's interesting how much shifting motions just become muscle memory. I shift without consciously thinking about which finger to move. And steering is the same way. Bikes have a learning curve.
For the rear derailleur, my Campagnolo 10 speed shifters have a thumb button to go smaller cog, and one paddle to go bigger cog. So when I first rode my Di2 bike, I was waving my thumb in the air next to the shifter for a smaller cog, or pressing the wider bottom shifter paddle for a larger cog shift. Neither was correct, of course.
After a couple of rides, it was all automatic. And now I can switch between bikes and pretty much instantly convert to that bike's methods.

Shifting front and rear more or less together is doable according to one first-ride reviewer, you press both paddles to shift the front then let off one paddle which shifts the rear.
One comment many first-ride reviewers make is that the shift speed feels slower than di2 or mechanical. I keep waiting for a reviewer to point out what seems like the obvious reason for this. Since pressing both paddles at once shifts the front, a very fast response speed to pressing a single paddle would lead to unintentional shifts if you mean to press both paddles at once but instead press one very slightly before the other.
In any case I hope the system turns out to be great, options and innovation are always good.
We'll have to see user reports of the Sram shifters in use. This makes sense, I wonder how many milliseconds it waits on a back shift to see if the front is going to be pressed too. Or I suppose it could start shifting the rear immediately, then shift back to the original cog if the front gets shifted instead. It probably wouldn't be noticeable to the rider.
