Probably because these companies operate in many countries.
Typically, this is done by incorporating separate corporate
entities in each country, and then managing them using
majority share ownership or a majority of seats on the 
board, or just by contractual means. This means that
often these so-called subsidiaries are only partly owned
by the mother ship, and may truly be independent organizations
that have contracted to use the mother ship's brand, and

In fact, it is common for MotherShip France SA, as an
example, to be a holding company that is connected to
several other corporations one of which owns a data centre,
one of which employs data centre ops staff, one of which
employs sales staff, etc.

With this kind of scenario, it doesn't take too many 
countries, plus a few acquisitions, to push a company
over the 200 org limit. And note that the limit is
projected 5 years from now, so any company with 
international expansion plans, or acquisition plans,
should have no trouble meeting the guidelines.

Five years is a long time. Few companies actually have
much of a five year plan in any kind of detail. My recommendation
to everyone is that if the 200 org limit is a factor in
not getting the allocation you need, then talk to your
CEO and explain the benefits of taking time to brainstorm
and formally develop a five year vision, which you can then
turn into a five year plan.

Anyone who is doing IPv6 deployment today is a visionary
business pioneer, and stands to do very well when the IPv4
address crunch impacts old-guard ISPs. Even if you only
sell against the old-guard using FUD, you will still sign
contracts and do much business. 200 organizations is not
hard to imagine for a visionary IPv6 business pioneer.
