Ive never needed to look any further than iPhoto for photo management so I 
wouldn't know ;)

iPhoto duplicates the file both on the disk and in the photo library (at least 
5.x does). If Picasa uses a method of re-applying effects every time the photo 
is loaded a library of 100 photos all edited would take forever and a day to 
load on anything other than a decent G5, especially if you are taking 6MP or 
larger photos. I doubt therefore it works like that, unless the programmer was 
smoking something dodgy at the time he wrote it!
