Are other players minions not Allied Persistent Reviving Minions (for Unstable Bonds)?

As per title, for the purposes of Unstable Bonds, while playing in coop, are other players persistent reviving minions (let’s say Skele Warriors from the Sceptre) not Allied Persistent Reviving Minions?

We tested with my coop party member, sitting in hideout with me, with my popcorn Skele warriors. He did not get any volatility stacks from my minion pops.

Does this mean allied players minions are not Allies? (Does this mean I can’t support his minions with my sceptre?) Why would the language on Unstable Bonds specific allied persistent reviving minions instead of “your” persistent reviving minions?

We thought we had a cool coop interaction there, with me feeding him minions for volatility then using his volatility to feed his Iron Ward. Too bad it doesn’t work
