I'm not so sure that sfdisk is creating cascading logical partition
tables, at least not because of this:

       Note that the LBA "Start" sector is 1 for each of the logical
       partitions.  Unless sfdisk created overlapping partitions (which I
       think we would have noticed), that implies that each logical
       partition lives at the beginning of a distinct extended partition.

Every linux system that I have handy has an lba start sector reported
like this by fdisk's expert mode.  This implies to me that either fdisk
is broken, the field is meaningless for a logical partition, or that
there are indeed cascading extended and logical partitions, but "they all
do that".  I don't know enough to know which of these is true.
