The assert was meant as an additional check to the assert in link.c:198. The reasoning behind the assert in link.c:198 is that once you've obtained a write lock on a vmnt, you can't get an additional read lock on the same vmnt. However, that does not always hold for the assert in path.c:281 where the situation could be that you've obtained a read lock and managed to get another read lock (this is possible). In other words, the assert in path.c:281 is not the right place to check for that situation.
