There's no way to know that without inspecting the mesh (or getting the author to explicitly tell you it's one piece). Meshes must be made with their specific purpose in mind: if a mesh needs to get simulated, you need to take that into account when modeling it.
Oftentimes, meshes that look like they're one piece actually are not. If you import them in Blender or other software, go to face select mode, and move some faces around, they'll detach from the rest of the mesh right away even though they looked legit. This is because they don't share vertices with their neighboring faces.
On addition to this, many meshes are non-manifold (thus not supported by Obi Cloth, and many other physics simulators). This is a topological property that in short, means the mesh surface can't exist as a real object. This is a huge no-no for a lot of practical purposes: physics, certain rendering algorithms, 3d printing, etc. Here's a link that explains it better than I can:
