You're right that in your particular data case --one word per line--
arr2 is always of length 1 => you could use arr2[1].  But creating
the arr2 array via split() isn't even necessary since arr will print
out in the order specified in PROCINFO["sorted_in"]:
--
$ cat test.awk
BEGIN { print_file_words("data.txt") }

function print_file_words(file,  i) {
  ORS = " "
  PROCINFO["sorted_in"]="@ind_num_asc"
  while (getline <file >0)
    arr[$1] = $0
  close (file)

  for(i in arr)
    print arr[i]
  ORS = "\n"
  print ""
}

$ gawk -f test.awk data.txt

WRT close() you should do it whenever you're finish reading from a
file OR command.  WRT user-defined functions, variables intended to be
local to the function should be declared otherwise they become global
variables; try removing the "i" from the function print_file_words()
definition and tacking on the following to your code:

  END { print "i =", i }

which will print "i = your" as the last line of output.
