Moore was only around for season 6. And probably only a couple weeks of season 6. They did all their resource episodes already in the first 5 years, and whoever was in charge of the writers room was probably sick of turning down those pitches that Voyager was running out of this and had to put the ship into danger to get it because all the shops were shut, and demanded a fresh take.
He produced Equinox part 2 and survival instinct and then RAN.
I'm assuming that the season 6 stories, barge of the dead and survival instinct which he was responsible for where submitted while he was still producing equinox or survival instinct. (Typing while referencing. Shut up.)
Survival Instinct is like almost the worst episode of Voyager ever.
