But Jake doesn't trigger twice. Jake can't perform a focus action without placing a focus token. So, you can't separate the "performing" part from the "placing" part to create two triggers.
Why not? Apart from it being inconvenient, why wouldn't you consider them separately?
If you had an ability which triggered only from taking a focus action, would that trigger? Sure - you took the action.
If you had an ability which triggered only from being assigned a focus token, would that trigger? Sure - you were assigned a token (as part of the action).
The fact that the token assignment comes as part of the action does not mean it doesn't qualify as its own trigger.
That's the point Smuggler brought up - Jake has two possible triggers, and if you do the first one, it will always result in the second condition. It's a separate opportunity, and should trigger it separately.
Pretty obviously not intended (even by my own RAI standards) but there are two separate triggering events in there.
