Making the assumption that Gerard did not have Vollstandig was not stupid it definitely made some sense i mean Pernida is also one of the Soul King's parts and it did not possess Vollstandig clearly, So making the correlation was not that absurd considering Shonen manga's often follow these kinds of patterns. I do believe however that this is Gerard's Vollstandig considering the change in appearance and the name.
