Way quicker? 

If you write it from top left, to top right, then across to lower left, you can cross it on your way to your next writing

It's an extra stroke you have to lift your pen with to make. Idk, when there are entire letters and numbers that only consist of one pen stroke, adding another one on top of the two that make up a 7, while not *that much* longer makes a difference when you're writing a lot imo.
