Take a close look. The expression consists of three main parts:
 - item
 - [@title != '']
 - [following-sibling::item[.........]]

The index collects item elements with non-empty title attributes. This is what your template selects 
as well, by the combination of the template match and if test.

But I added a second condition to the item elements that are collected. The second requirement is 
that there must be a _following-sibling::item_ that has a fieldentry = 'OE'.

That is why I called the index 'OE-related-items' instead of 'OE-items'.

In your own code you select the OE-items first and then look for the related items, but I had to 
reverse this for the index. preceding-sibling outside a predicate as in: item[fieldentry = 
'OE']/preceding-sibling::item[@title != ''] is not allowed (the parser told me)...
