Very strange behaviour: Using PHP-text option, new nodes won't create proper text from $title

Using PHP-text option, new nodes won't create proper text from $title.

BUT, if I edit the PHP-text-code and change my varible once from placeholderx to placeholdery, the new node that generated a non functional Image, now generates a proper text. But if i make a new node again, it won't work and I have to reset the PHPcode with a new varible name again... ?

This is only on $title, and not on my body-code...

The PHP-code in question:

TITLE

foreach ($image_context['referring_entities']['field_wordimage']['node'] as $nid => $node) {
  $titlexqx = $node->title;
}
return $titlexqx;

BODY

foreach ($image_context['referring_entities']['field_wordimage']['node'] as $nid => $node) {
  $other_field_value = $node->body['und'][0]['value'];
}
return $other_field_value;

Is my PHP code wrong somehow or is it an issue with imagecache Actions?

Please advice!!
