If you look at the final result of page 79, you'll notice the third panel was flipped horizontally. This decision was made because the panel composition "flowed" better that way.
Instead of the bottle/blood's direction going from right to left, it went top left to bottom right, making it easier for the reader's eyes to follow to the next panel, which is on the bottom right.
That's how comics work :) (or rather, that's us comic artists trying to do cool stuff yo)
