I don't know what he has done, but it's possible to stack SMT capacitors if 
great care is taken.  This will work for the line-in and mic-in changes, but 
I cannot see how stacking C9/C13 will work for the headphone output change. 
If he's accomplished that task, God bless him.  Myself, I've found it takes 
a great balancing act to stack SMT parts and hold the new component in 
place.  I'm not the world's best SMT re-work guy, so others may have 
developed better eye-hand coordination skills.
