From what I understand, the first mined block was not done by Satoshi. He waited until someone else had mined it until he then started mining himself. Allowing an outsider mine the first block set the hashing difficulty rate independently.

This, as it turns out, was a key aspect for the Howey test as it clearly demonstrates that there was no specific "insider" allotment

(Note: I haven't watched the video, perhaps it goes thru this....)
