Two 208/120 Secondary Feeds to Same MDP

I have a facility with a MDP that is receiving two wye connected 3 phase secondary feeds in to this MDP from three single phase transformers, 100KVAea, 12KV primary Wye to 208/120 volt secondary wyes.

I have never seen this before. Usually a 3 phase transformer bank may feed one of it's secondaries to one building and another secondary to another building, but not to the same MDP in the same building.

Why was this done??

Xfmr bank is probably capable of supplying over 800A at 208Y/120V.

To use this 800+A, were conductors simply connected in parallel? If so,this is not at all uncommon.
