If that were the case, then they'd need another episode to explain the bamboo tree from the last episode. Which basically kills off any making-of "Asahina Mikuru no Bouken" episodes.
From what I hear, they're probably airing Day of Sagitarius for more Yuki love rather than explaining some of the treasures in ep 9.
Then again we won't know what's being aired the week after until next week
On second thought, I'd rather just enjoy what we're shown rather than guessing what they'll show next.
