What do you mean by spaces? In screenwriting software, those lines would go one under the other without any real spaces between the lines if that's what you mean.
Technically I would say that formatting is correct if you need to make it obvious which member among a group is being addressed i.e. using (parenthesis). Though it's not always necessary if it can be implied from the situation or response.
Alternatively, to make it clearer in your example, I would simply add the addressing action to the preceding "action" text and say it like this -
...John looks to Jake.
JOHN
What you drinking?
