Using online redefinition on a partitioned table with a global index, leaves the global index UNUSABLE once the redefinition is complete.
The issue is cause by using online redefinition:
However, it does not include the UPDATE [GLOBAL] INDEX clause.
What the document says:
Internally while finishing the redefinition index must be updated. The documentation for alter partitioning tables as follows:
Partitioned Tables and Indexes
Maintenance of Global Partitioned Indexes:
By default, the following operations on partitions on a heap-organized table mark all global indexes as unusable:
These indexes can be maintained by appending the clause UPDATE GLOBAL INDEXES to the SQL statements for the operation.

* The index remains available and online throughout the operation. Hence no other applications are affected by this operation.
* The index doesn't have to be rebuilt after the operation.
