The issue is in your array definition:

$arrayAssoc2 = array(
	'one' => '1: some val',
/*...*/
	'one' => '2: some val',
/*...*/
);

so you're overwriting the key 'one' again. If you replace the second 'one'
with 'four' it works as you expect.

Description:
------------
The first key/value pair should, in theory, not be present in the result array.

Test script:
---------------
$arrayAssoc1 = array(
	'one' => '1: some val',
	'two' => '1: another val',
	'three' => '1: and another val',
	'four' => '1: fourth val',
	'five' => '1: fifth val',
	'six' => '1: sixth param',
	'seven' => '1: sixth param',
	'starwars' => '2: lightsaber'
);
$arrayAssoc2 = array(
	'one' => '1: some val',
	'two' => '1: another val',
	'three' => '1: and another val',
	'one' => '2: some val',
	'five' => '1: fifth val',
	'three' => '2: and another val',
	'seven' => '2: and another val',
	'starwars' => '2: lightsaber'
);
var_dump(array_diff_assoc($arrayAssoc1, $arrayAssoc2));

Expected result:
----------------
array(5) {
  ["three"] => string(18) "1: and another val"
  ["four"] => string(13) "1: fourth val"
  ["six"] => string(14) "1: sixth param"
  ["seven"] => string(14) "1: sixth param"
}

Actual result:
--------------
array(5) {
  ["one"] => string(11) "1: some val"
  ["three"] => string(18) "1: and another val"
  ["four"] => string(13) "1: fourth val"
  ["six"] => string(14) "1: sixth param"
  ["seven"] => string(14) "1: sixth param"
}
