En effet c'est faux
Quand un ou plusieurs permanents quittent le jeu, le jeu "revient en arrière" juste avant la mise au cimetière pour voir ce qui a pu se déclencher et donc à ce moment-là, tous les effets continus qui s'appliquait aux permanents qui ont quitté le jeu s'appliquent toujours et donc la capa va se déclencher et ne sera pas contrôlée par le propriétaire de la carte mais par son contrôleur au moment où elle a quitté le jeu.
410.10d Abilities that trigger on one or more permanents leaving play, or on a player losing control of a permanent, must be treated specially because the permanent with the ability may no longer be in play after the event. The game has to “look back in time” to determine what triggered. Each time an event removes from play or changes who controls one or more permanents, all the permanents in play just before the event (with continuous effects that existed at that time) are checked for trigger events that match what just left play or changed control.
Example: Two creatures are in play along with an artifact that has the ability “Whenever a creature is put into a graveyard from play, you gain 1 life.” Someone plays a spell that destroys all artifacts, creatures, and enchantments. The artifact’s ability triggers twice, even though the artifact goes to its owner’s graveyard at the same time as the creatures.
