I cannot speak for the authors, but what I understand is:
Sparse allocation tries to make sure an organization get
contiguous IPv6 space,
but prop-099 tries to make
sure each PoP within an organization also get contiguous IPv6 space.
For example, under the current situation, when an
organization gets an /32, and
there are 4 PoPs in this organization, he will sub-allocate /34 to each PoP,
next time this organization get another /32, and also
sub-allocate /34 to
each PoP, although the 2*/32 can be aggregated as /31, each
PoP's 2*/34
can't be aggregated since they are from different /32.
In the above example, sparse allocation tries to ensure the
2*/32 are contiguous,
but prop-099 tries to ensure the 2*/34 are
contiguous.
