In theory yes, probably that's the intention. Several other companies claim the same. Interviewers are nice and everything, however this whole process is flawed, and the post nowhere depicts the reality.
Practically, interviewers more often don't care anything other than solving the problem. Some are checking their emails while the candidates solve the problem, some are just trying to give the most obscure problems using exotic data structures, and some are simply too lazy to pay attention. So, I would say whatever the procedure is, there is an enforcement problem.
It is what it is with most companies. So we leetcode like hell, and hope for the best.
EDIT: I've had much better interview experience when the interviewers belong to the team I will work for. I think there is more clear incentive for interviewers to be more interested.
