Hi,
If I read this :
(http://www.apple.com/pr/library/2013/10/23Apple-Introduces-Next-Generation-iWork-and-iLife-Apps-for-OS-X-and-iOS.html
and particularly this section the very last line:
The notion of existing users does not imply a specific release.
Hence anyone owning a previous person of iWork that is usable (i.e. installed and runs) should get a free upgrade.
That's what I read.
You're trying really hard to read something into that which isn't there. It is obviously not addressing every possible situation, including yours.
