Cleaner is referring to no propane tank and open flame. Burning anything is a messy process that has to be kept FAR from gunpowder. Burning always produce impurities, flame directly contacts with brass vs. no touch method with induction.
Electrical is always more precise than gas. Can't say if it makes a difference for annealing but still cool to set timer to .1sec accuracy.
Great if you can find the article. Do wonder about the Annie's horseshoe in that the field can not be uniformed. Seems the field in a coil would be uniformed thus no case rotation required. Any EE out there that can help explain electrical/magnetic fields in a coil. In the new Annie vid with the coil they specifically mentioned and show the brass being self centered by the coil's magnetic field.
Here's the industrial brass induction vid. Seems the brass is rotating. Go to 1m24s (embedded vid is NOT jumping there properly)

I will respectfully disagree that induction annealing is any cleaner or more precise than annealing in an open flame.
I will agree however that it is twice as fast when comparing a Giraud with a Fluxeon Induction Annealer and a Giraud annealer with an open flame.I am trying to find the article that I read somewhere that the author was getting worse results with induction annealed cases than with cases which were turned in an open flame.
He went on to say that the results were due to the induction anneler not annealing the cases evenly because they were not rotating. When he would rotate the cases in the induction annealer the same way the Giraud does his results were the same as with a flame based annealer.
If I can find the article I will post it.
If you can control the speed of the case and regulate the the gas pressure you will have repeatability.
Below I have posted a picture of my Lapua brass that has been fired 18 times. It is now prepped and ready to be loaded for the 19th time.These cases have not been cleaned after annealing. They were cleaned in stainless steel pins prior to annealing
I would like to see how you can get any cleaner than this with an induction annealer.
