That is because you are nesting two loops, e.g.
foreach (array(50, 65, 97) as $freq) {
foreach (array(65, 45, 66) as $orient) {
// do something with $freq and $orient here
}
}

Then you should use only one loop, e.g.
$pairs = array(array(50, 65), array(65, 45), array(97, 66));
foreach ($pairs as $pair) {
list($freq, $orient) = explode($pair);
// do something with $freq and $orient here
}
