It appears you are correct. I traded emails with Vinnie, and he essentially says the same as you:
Lacto does in time create a pellicle or at least a pellicle like cover over the beer. It will ferment sugar out, but, Im not sure of how much if any alcohol production is created, Ive seen Lacto only drop the SG of wort, but, at the time we didnt have a lab so I couldnt check for ABV in the lab. But, yes, it can drop the SG. It is actually a really good test to see how Lacto affects the flavor, youll see that it is a thin flavor, that is why I like Pedio as it is a richer flavor.
The other point, about lacto and ABV is in responce to the post by Evan about if Lacto ferments.
I have to admit I was wrong in my previous post contradicting flyangler18. Hope this helps others.
