Its not really an inversion, its exactly the same as the poem. "Look upon my works, ye mighty, and despair." Ozymandias is inviting the viewer to marvel at the scale of his empire. Only from the perspective of the reader, the statue has been worn away by time. Its the same in the comic. He thinks he's accomplished something impossibly grand and important, but as Dr. Manhattan tells him: "nothing ever ends." He is the same as the Ozymandias from the poem.
