TBH I don't really understand what that second sentence is trying 
to say, so I can't judge whether it's misleading or not.

How about something like

  “Any packages they define will be added to the pool of available 
  packages.  Standard package specification rules apply: when 
  given a package name without an unambiguous version number, Guix 
  will always pick the highest version of that package regardless 
  of where it came from.”
