Yea, if this is like the many other similar studies, they are restricting the antibodies counted to the ones specifically made to match the spike protein. Natural immunity makes less for the spike, but more overall, both in breadth of type and total number. Artificially limiting the count to one type of antibody is like claiming to be richer than Warren Buffet because you have more cash in your wallet than him in line at McDonalds, and ignoring the fact that your wallet contains your total net wealth.
