That looks like reverse loop to populate an array followed by a call to
reverse(). He certainly goes to a lot of trouble slow things down.

You certainly go to a lot of trouble to do nothing.

Certainly Function.prototype.apply can do anything that
Function.prototype.call can, so the thrust of my inquiry is: Does the
absence of the former really make the entire following code
unnecessary or useless? Or did the author assume that any browser
which lacks call would also lack apply?

Yes, if call is not there, forget apply.
