Will 2 of the same Druid still get the buff?

Say you have Maokai and Ivern on the board, so they are proc-ing the health regen Druid buff. If you put another Maokai in, will BOTH Maokai’s benefit from the health Regen, or will it only affect the 2 druids proc-ing the regen (og Maokai and Ivern)??

I’ve been told both. Either “ALL druids get the buff so it would be good to put in multiple tier 2 Maokai’s until you get tier 3,” or I’m told “all other synergies don’t count multiples of the same champion so only one Maokai would get the Druid regen.”

Haven’t been able to find any answers on google and I’ve got a bet with a cousin that I would love to resolve. :D

EDIT - my question is not if two Maokai’s will trigger the buff. What I mean is if you have 3 druids, either 2 Maokai’s and 1 Ivern or 2 Ivern’s and 1 Maokai, if the repeat champ will still get the health regen.

I’ll try to explain it better. Say you are level 3 and can have 3 champions on the board. All you have is one Ivern and two Maokai’s, so you have a second Maokai that is not due to woodland buff on the board. You have Druid buff active because you have both Ivern and Maokai on the board. But does the SECOND Maokai’s health regen too? Keep in mind this maokai is just another maokai that was on your bench, it is not a duplicate from woodland buff.
