Secondly, quality of lifts and spins are reflected in the GoE, unless if its a massive fall that would affect the entire performance.
Lastly, lines and posture does not equal to the entire PCS
Ever since 6.0 got changed to CoP, lines and extension no longer (at least IMO not supposed to) have the huge importance they do in 6.0. One look in the program component overview and you would notice that line and extension only truly factor in 1/5th of the PC score (in performance/execution) and even then its still only a portion next to emotion, variety in tempo and a bunch of stuff unrelated to lines. I also never knew that "elegance" is now a part of program component...I've always thought that as long as your movements match the program and done at high quality then it would be marked well.
IMO this is how it should be...its figure skating, not Ice Ballet with jumps (just as it is not "ice jumping"). Theoretically, someone could choose some rock music and skate with horrible lines and should still be able to get decent SS/Transition/Choreo/Interpretation mark if the judges are marking the program objectively. (and not based on pre-determined types of "good" programs).
Back on topic however, I think G/E was placed right. They did get lower PCs in comparison to E/L, and its was the higher level TES that puts them ahead.
