Programmatic removal of auto-cloned inline tags

I am developing a plug-in that merges segments into one. Some segments contain auto-cloned tag pairs, e.g.:

 

This is a <pt15>test</pt15>:

<pt15>Attention</pt15>!

 

When merged the consolidated segment looks like this:

This is a <pt15>test</pt15>: <pt15>Attention</pt15>!

 

But it should look like this, which is what you also get when merging those segments in Studio manually.

This is a <pt15>test: Attention</pt15>!

 

For merging I am using a function that looks as shown below. The MoveAllItemsTo method also inserts the tags with the sdl:autoclone property into the enlarged segment. Can anyone think of an easy way to exclude the auto-cloned tags?

 

 

        private void MergeFunction(IParagraph paragraph)

        {

            var segments = from item in paragraph

                           where item is ISegment 

                           select item as ISegment;

 

            int i = 0;

            segments.ToList().ForEach(item => 

            {   

                i++;

                var sourceSegmentPosition = item.IndexInParent;

  

                if (i > 1)

                {

                    item.MoveAllItemsTo((IAbstractMarkupDataContainer)segments.First());

                    item.RemoveFromParent();

                    item.MoveAllItemsTo(paragraph, sourceSegmentPosition);

                 }

            });

        }
