I believe what is against the law is working as an unlicensed 1099 employee, not a 1099 licensed contractor. There is a huge difference.
I think you are correct.
It only specifies apprentii, journeymen and master electricians. (for 1099)
You have to be a licensed contractor to get paid (legally) directly from a customer. To be a licensed contractor you must employ at least one licensed master electrician and that person must be paid 1040 wages along with the rest on the list.
In short, it makes side jobs illegal.
