Well, if I understand it correctly: (assuming /foo is vfsmount A) $> mount --make-shared /foo will make A->A $> mount --bind /foo /foo/bar will create a vfsmount B based off A, but because A is in a p-node, A->B, B->A. Then, we attach B to A in the vfsmount tree, but because A->B in the propagation tree, B also gets a vfsmount C added on dentry 'bar'. Recurse ad infinitum.
