I think the specifics of what he did should be on the surgical report. You can ask for it. But I think you're right. He may have felt that a wider cut was necessary because he felt or saw cancer and he took more fascia that he normally does. Comparing one surgeon to another what can be defined as wide to one surgeon but not so much the other.
The down side of wider cuts is the void that is left behind can cause varied results resulting in stress on the urinary sphincter that can cause incontinence. This is where the surgery is an art per se. Good surgeons can do a better job than others in preventing such things by the way they "close". Another known issue can be fistula. This is where the rectum can develop pockets in the voided space where the prostate used to be. Again the close can make a difference. I've seen a lot of presentations on these aspects and they can matter.
One more issue of a wider cut is nerve sparing can be limited. This both ED and incontinence can result.
Most surgeons will attempt to leave the surgical site as close to the way they found it as they can to avoid side effects.
