Why doesn't Ekko's "clone"(?) grant vision?

I've watched a few videos of Ekko gameplay on the PBE. It's possible that this has been addressed and may even be slated to be fixed before release, but I have seen Ekko's clone, or whatever you would call it, trailing around the corner, or even in a straight line, and then he's gone into the fog of war! Why would anyone want to ult blindly into the fog of war!? I understand that this really can come down to knowing when is a good time to utilize your ultimate and vision control. I also understand the huge benefit that full vision around the clone could give the player, or the team for that matter, so the vision would have to be scaled down a bit, but I still believe it would be important.

The other thing I see as strange about Ekko's clone is the fact that the enemy can see it. What if you are trying to lose the enemy by hiding in a bush? They will just watch your clone, and the path that leads to the bush and hiding is useless. Now, a wise player could use this as a bait, but still. Maybe expecting both of these changes is a lot, but I feel that these changes really just make sense.
