The cursive thing is almost certainly because he's using fountain pens. Pencils and ballpoint pens lend themselves to printing more easily, because they require pressure to write, and when you let the pressure up between letters, the line stops. The first time I picked up a fountain pen and tried printing with it, I found all my letters were connecting whether I meant them to or not, and I suddenly understood why cursive exists. Everyone who's learned cursive in the ballpoint pen era has been unwittingly taught a performance optimization for a tool they're not using.
