persona, yes, i think that when you play this passage starting with five you are FORCED to play more into the keys. this is good for fast, light playing. it is harder, imo, to play the notes evenly - though, so you are forced to just wing it and hope it sounds good. that is due to the many various lengths of fingers and types of hands.
i studied at two colleges and find no real significance there because two different methods and ideas were taught. the one was using cortot fingering ideas and a more 'romantic' setting and the other was a combo of international ideas that did not fit into a 'romantic' setting but a post modern one. basically, there is a return to tonality - i hear - but a definate tendency to reject formulated theories for one's own discoveries of 'what works' even if it is contrary to everything you've been taught. which brings you back to square one - your own discoveries.
i learned from my last teacher to think for myself and not blindly accept everything - although having a foundation to build upon is nice! i'm not one of those people who would discover all this information on my own (whereas other pianists - famous and not famous - have). for instance, i learned that when you play a lot of fast notes - there is not the urgency to play a ff at a beethovenian level in liszt. you can simply play forte and it comes out ff naturally because of the number of notes. therefore, you can lighten your touch and play faster, too.
this type of information is invaluable to people who want to progress in their technique. but after 4-6 years of this - you go off on your own and find another teacher that tells you to break a few rules. to play with a very flat hand was a huge wondering for me. i thought, 'i'll lose all my control.' well, you really don't. and, you actually gain some insight into 'bel canto' instead of strict bachian type playing which works well in church but not in liszt or chopin.
