I have come across an existing part that has given me cause to ask why which can be a bad thing sometimes because I don't get any work done.

I have always started a sheetmetal part as sheetmetal while most of the guys here learned to create solid parts and then convert. Today I came to a part that has been crated as an extrusion, converted to sheetmetal and then the  bends are flattened followed directly with process bends. I have seen this here before but today it struck me as extra features and I had time to question it. Can someone explain what would be gained by that? I can see flattening bends for a feature that needs to cross the bend line and then folding the part back but I am at a loss for this.
