I didn’t download the .pdf, but it looks like this was probably conducted by paying volunteers for all of their volunteer work. If someone got paid for half of their hours volunteering, or had two positions doing very similar work and then one of them started paying, I’d expect this effect to diminish.
The study concerns how many hours per week were spent volunteering; some was paid, some was not, though presumably a single organization would either pay or not pay volunteers, rather than both. Paid volunteers worked less per week overall.
The study I referenced was not the one I intended to reference, but I have not found the one I most specifically remember. Citing studies is one of the things I most desperately want an eidetic memory for.
