In the Taichu's recognition of the First Emperor, there was no reason; it was a thought that emerged when the two revered figures of the Shen Zang Cult saw the Heavenly Halberd.
Given their status, they wouldn't have such thoughts without cause.
Otherwise, why don't the Celestial Emperor Jiang Li of World 390 and Slacker Jiang Li of World 809 have the Heavenly Halberd?
What it means to be recognized by Taichu is unknown.
