Your perspective of what caused those white marks is certainly possible, and I don't take issue with it, DUNE; it's only that I interpret a different possibility as being more likely (and I certainly acknowledge I could be wrong in that assessment).
And so regarding my previous comment, just by way of clarification, my view is that the white on the walls seem to be too erratic to have been caused by white paint (or plaster) smeared onto that rock, e.g., by a rag. Rather, I'm thinking it's possible that after the red paint run occurred in that horizontal joint, there was an attempt to wipe it off with a rag, but due to an excess amount of paint, the paint welled up while being wiped, and the roof plaster (or porous limestone block) absorbed a lot of the red paint as it became smudged by the rag and left residual stains here and there on that roof block. The stains which couldn't be removed by further rubbing with a rag. In that case, the only way to get the stains off the wall was to actively scrape it off, thereby leaving the erratic pattern of white showing amidst a significantly darker (older?) surface.
Regardless of how it happened, why would it be so important to wipe up the paint run? If those white marks are indeed attempts to scrape off stains of absorbed paint, why would the removal of those stains be so important?
In any case, it seems we are in agreement that the white marks on that block do not follow the logic of pressure of the roof block against the wall block.
How can any of us ever know, when all we can do is think?
