for j = n − 1 to 1 step − 1 do
does this means for all j in [1 .. n-1] or [2 .. n-1] ?
Umm, don't you mean "if n is 6"? Also, most languages would do a loop where the range doesn't overlap as not doing any loops at all, not as going clear around number space until it wraps and hits the ending value from the other side.

A:
If n=5 then the for loop is executed 4 times with J equal to 4 then 3, then 2, and finally 1 in that order
