Shawn won because of his GOE. In his LP, he got plus GOEs on all the elements but the URed 3A. All of his jumps but 3A got plus one or greater GOE, including 1.6 on 3Lo and 1.8 on 3S+2T+2Lo. Likewise, he got level 4 on all of his spins with high GOE. His TES was like 10 points higher than the base value, which means that he is technically superb in the elements that he did.
I hope that he will become a bit faster in his skating so that he can get better PCS and will increase the levels on his steps and hopefully land 3lz more consistently so that he can have two of them in the program instead of two 2As.
