Oran-Rief Hydra vs Zendikar's Roil matches

So since about the last patch or so Zendikar’s Roil has been allowing more than 1 simultaneous match.

For example if a spell like Animist’s Awakening causes two matches of 4 green gems at the same time you will get 4 elementals spawn. Oran will only gain a single +2/+2 for the green landfall. This could be by design if “green landfall” and “match 4 green” are considered different but it seems at least inconsistent.

I’ve noticed this too while using Animist’s and the “Retreat to xyz” supports. It only triggers one landfall even if 2x match 4 occurs simultaneously.
