"The devil made me do it"
There's a difference between having infinite power and being omnipotent . Apparently you haven't actually understood what the person in the scan wanted to say when he made that analogy so let me elaborate it for you . Let's just say that there is a person who has infinite control over Gravity (The 1,2,3,4 example) and that there's also a person who has infinite control over Electromagnetism (The 2,4,6,8 example) . Now , if another person exists that has infinite control over the four fundamental forces (The whole numbers example), those being Gravity , Electromagnetism the Strong and Weak nuclear force than this being surpasses the other 2 beings since it encomasses their powers also .
In order to be omnipotent it means that your power must be all-encompassing , to include all areas .
I can easily prove that the cosmic cubes aren't omnipotent since they don't have infinite power over certain areas . I can also prove that Infinity Gauntley doesn't mean omnipotence since it's inferior to someone and also doesn't have control over all aspects .
On the other side , it's quite easily to prove that Spectre had total and infinite control over everything because The Presence/God stated it :
"His power once limitless , is now dormant , untapped (reffering to Pre-Crisis)"
"Yours was the Power Omnipotent"
"Indeed your Power Omnipotent was so great , so All-Encompassing"
It's not that hard to comprehend .
