I have no idea. During 3 rides after the moment when the cut appeared, the sealant continued to spread as a very thin jet of spray over the frame and rear brake - it never really seals, although it blocks the air to flow out. My intuition says that the issue is the tire pressure, which is higher for road bikes compared to MTB. If my intuition is wrong, then I have no idea about the real reason.
