JTL Lando Interaction

Quick question on this type of interaction with JTL Lando.

For units that create tokens in space, ie Poe Dameron, how is that resolved with Lando? Does the when played occur after fully resolving Lando's action, or is it nested?

Playing that type of unit gives you a space and ground unit after the when played.

My thinking is that the When Played doesn't happen until after fully resolving Lando, but I want to clarify that before trying to play it in person.
