I remember this being implemented from my days in PI/open development. It was all about performance when editing very large items. If the data was stored as a single dynamic array, processing is easy but becomes painfully slow with massive records. I recall comparing ED with another editor that did not break the data up in this way. When the data was over 100,000 lines long (I cannot remember what this huge item was), the performance difference was huge. Although processors are now a lot faster than when this was written over 20 years ago, the gains are still worth having.
