Section 6 (1997-FC-3-6) specifically notes that "for the purpose of this resolution the "home territories" described above shall include each home territory in which a club is playing [...] as well as [...] LA".
You excised a particularly relevant part (emphasis added):
"6. That for purposes of this resolution the “home territories” described above shall include each home territory in which a club is currently playing (which, as of the date of this resolution, includes Houston) as well as the areas
that would constitute the home territories of clubs
playing in Cleveland, greater Los Angeles (including Orange County), Nashville, and Memphis."
This section is outlining the rights of the
future team that moves to the LA market; namely, that another NFL owner could not purchase a major sports league franchise in their market. The words "would" and "playing" indicate this.
This is perfectly consistent with the other sections, which explicitly state that 1) LA belongs to no NFL
club, and 2) NFL owners may not buy sports franchises in the markets of other NFL clubs.
