Clarification of Polemarchus's Law

At present, Polemarchus's Law reads:

If a Disciple feels that another Disciple deserves a change in their soul's aspects, as a result of their behaviour in the Republic, then they may add or subtract five from any one of those aspects, to a minimum of zero. This may be done often by a single Disciple.

Where do people stand on a question of rule interpretation -- may a Disciple once per day change the soul aspects of just one other Disciple, or may a Disciple once per day change the soul aspects of every other Disciple as long as they only change each Disciple once that day?
