It should. There is no explanation for it. It takes 10 seconds to commit.
Technically under the current rules there is nothing prohibiting me from committing for 20 different players.
The reasoning for the rule as it is now is for committing a doubles partner when you are waiting to see where you can make main draw cuts into... sometimes managers don't keep their lists updated and sometimes it comes down to the wire knowing where you and your partner can get in directly and when that happens it may be at a time where they cannot be on a computer to commit themselves.
Or if your regular doubles partner is on vacation and unable to commit themselves for the week when they return
There are legit reasons for this rule as long as its not being abused
