Projectile change question.

"Projectile skills no longer "shotgun". You can't hit the same target with more than one simultaneously-created projectile from the same source any more. They've been rebalanced around this."

(1)So If I have spark with pierce and faster projectiles GMP and the 2 sets of increased skill duration can only ONE of the projectiles EVER hit the same target?
(2)Even if they bounce off a wall or something?
(3)And does this mean the SAME projectile(if it pierces) hits the same target 2+ times?

Spark is a special case, whenever any of the sparks bounces it resets the state of all projectiles from the same volley so they forget which target was previously hit and they can hit it again.
