I mean, initially, sure. But if any of us spent a day with this I doubt it would be anything less than second nature. Brains are incredibly elastic.

Then it is a good way to train your foot / finger coordination.

As a drummer, I'd say you'd be surprised how fast people learn to sync feet with hands. It's really quite easy with a little practice.

Thanks for the tip!

This reminds me of my friend's father who decided to learn programming later in his life and signed up for a class. Incredulously, their language of choice of Perl, and so not two weeks later he comes back from a class and shows a handout that says:

     slkjs/sdfjks/\1jksok/j23kjdj\skjd

   is the same as 

     lkkd\kk////?!@

   except latter is shorter and easier to understand

The note was actually correct and the actual expressions made sense, but to an average person both looked like a line noise. Needless to say it was his last class.
