Exactly. These kinds of drill are not designed to replicate the conditions of an actual match, they are designed to develop physical technique and muscle memory. It's like saying that swimming laps is pointless for a footballer because they don't actually have to swim during a match; it ignores the other benefits of the exercise (or drill).
It's just something for the camera. Turned into a competition at the end where the player that missed went "out". Just something to keep players entertained.
You are not gonna get much muscle memory by waiting in a line and having a shot every 3 minutes.
Properly it would be each player on their own with a ball and a target. Better still would be one of those machines to launch balls at them.
