I have two computers running BOINC. Both of them had the program installed individually, but are logged into the same account. I saw under help the following question and answer:

I replicated an install to several machines across a network and now my points are not incrementing properly. What is wrong?

This is not a supported configuration. We recommend that each machine is logged into individually. If you have already completed this process and need a fix, you must go to each machine (other than the initial machine) and reinstall on each device individually.

Does this mean that there is a risk that the work units won't be counted properly because both computers are on the same account? Or does it mean that this is only a problem when all of them have the exact same installation used to copy the program onto all of the computers at once?

Thank you.
