As you can see in the 2.79 release logs, a lot of Alembic improvements have been made since 2.78c. Can you try with a recent daily build from https://builder.blender.org/download/?

Unfortunately, v. 2.78.0-git.020bbbb-windows64 behaves the same.

I can confirm this bug. The root cause is that the Mesh Sequence Cache modifier adjusts the vertices of the mesh directly. You can see this when you view the mesh in Edit Mode; the mesh will be deformed, instead of in the rest position as expected by the Armature modifier.
