QUOTE: ('K'' is Kajishima. 'T' is the interviewer. My apologies in advance if 
this comes through formatted oddly.)

K: If you put GXP and Tenchi Muyo! Ryo-ohki in order; GPX's time frame takes 
place a year after Tenchi Muyo! Ryo-ohki. The audience may be confused as to 
why certain characters show up in GXP. 

T: But GXP will be released before Tenchi Muyo! Ryo-Ohki 3rd OVA, right? Oh, 
I see, it's like Star Wars, where you'll release the latter episodes first. 

K: I want to put in some fun for those who watch GXP. It keeps them guessing, 
"What is this character doing here?" "Will this character be...?" Then have 
the secrets unveiled in later episodes.

An earlier segment of the interview makes it clear that by referring to 
'Tenchi Muyo! Ryo-ohki', Mr. Kajishima means all three OAVs, which he 
considers to 
 
be one chapter in the Tenchi saga.
