"Use T0As Ref Pose" doesn't work when FBX has two meshes with different bind poses

"Use T0As Ref Pose" doesn't work when FBX has two meshes with different bind poses.

See attached example assets

1. Download the attached assets
2. Create a blank project
3. Import the mesh titled "twobind_bothmesh.fbx"
4. In the import options, expand the advanced section under "Mesh"
5. Enable "Use T0As Ref Pose"
6. Select Import and open the skeletal mesh

Result: The mesh's head is not tilted to the side. The first frame of this fbx has a key with the head tilted to the side.
Expected: If "Use T0As Ref Pose" was working with a "two bind pose" fbx, then the head would be tilted to the side.
