Talon E and R Interaction [REWORK]

Was just trying out the Talon rework in a custom game and noticed that while invisible from ulting using Talon's E to vault cancels the invisibility and thus causes the blades to converge on Talon. This means you CANNOT use vault to come over a wall invisible and drop all your blades on someone, since they only converge on a target if you auto or Q them. If you want to pull off such an approach you need to flash the wall, which kind of seems to remove the best use case for the vault. Was wondering if this is intended functionality. Thanks,
