Onyx rewards, wrong recon used

When you hit onyx in ranked you get the weapon emblem and the recon helmet charm. My problem is with the charm, why is it the halo reach recon helmet? The lore for the charm is “see, you finally got it” which is a halo 3 reference. Recon in H3 was only for devs and given to a few special community members that made game modes or other featured content. That created “can i haz recon”, which the lore of this charm is referencing. I’m just wondering why its the reach version and not 3s version like the lore references.

Conspiracy theory, They just used the reach version because it was already made for the season and didn’t want to make the halo 3 version yet.
