Interesting phrase, "pushes down". Why would you think atmospheric
pressure pushes down?

At sea level the atmosphere pushes down with about 14.7 pounds of force
for every square inch of exposed surface. On the average man, this works
out to about 43,000 pounds, all the time. Why aren't your crushed by this?

He probably picked down since down is as good a direction as any,
unless, of course, he was thinking of someone with a big head whose
top surface area measures 4.5 feet x 4.5 feet.
