1. Is this because RMAN level 0 backup only backs up the blocks that
have been written, and escapes empty blocks in data files?

>>> Yes.

2. How does RMAN determine which datafiles to group together, to create
different backupsets? 

>>> I'm not positive on this, but IIRC it tries to size them evenly,
e.g. if you have 2 backup sets and have one 100GB datafile and 4 25GB
datafiles, it will put the 100GB datafile in one backupset and the other
4 files in the other backupset.
