As long as the router facing the end points is able to transmit a unique prefix per host in the RA then both of the cases below will work.

In the 2nd para of Sec. 4, it reads:

"The Unique IPv6 prefix can be derived from a locally managed
   pool or aggregate IPv6 block assigned to the First Hop Provider
   Router or from a centrally allocated pool.”

In the case the prefix is assigned from a centrally allocated pool, does this scenario include the following cases?:

o all prefixes assigned to devices on the same shared network may not be aggregatable into a single shorter prefix.
o /64 prefixes may be assigned randomly to different devices on different share network.

       Title           : Unique IPv6 Prefix Per Host

Abstract:
  In some IPv6 environments, the need has arisen for hosts to be able
  to utilize a unique IPv6 prefix, even though the link or media may be
  shared.  Typically hosts (subscribers) on a shared network, either
  wired or wireless, such as Ethernet, WiFi, etc., will acquire unique
  IPv6 addresses from a common IPv6 prefix that is allocated or
  assigned for use on a specific link.

  In most deployments today, IPv6 address assignment from a single IPv6
  prefix on a shared network is done by either using IPv6 stateless
  address auto-configuration (SLAAC) and/or stateful DHCPv6.  While
  this is still viable and operates as designed, there are some large
  scale environments where this concept introduces significant
  performance challenges and implications, specifically related to IPv6
  router and neighbor discovery.

  This document outlines an approach utilising existing IPv6 protocols
  to allow hosts to be assigned a unique IPv6 prefix (instead of a
  unique IPv6 address from a shared IPv6 prefix).  Benefits of unique
  IPv6 prefix over a unique IPv6 address from the service provider
  include improved subscriber isolation and enhanced subscriber
  management.
