Responsibilities and duties are like Rights and Obligations.
Article 1.2 clarifies what a role is entitled to do (i.e. processing and tracking tensions, purpose, accountabilities and projects).
When you’re on your own, you don’t have any obligations towards others (because there is no ‘others’). In most organizations this is not the case. A role has been granted to you by another role (or circle). So there are ‘others’ (roles, members, partners). Even within a decentralized context of a for-the-purpose organization there must be some kind of coordinating mechanism. This is where obligations come into play (duties in article 4.1: transparency, processing, prioritization).

It seems to me superfluous to have a purpose ‘enact [..] in order to realize the purpose of the organization’ (because that purpose was the reason that your role was established).
The same goes for ’taking into account the needs of other [..]’. The constitution is all about ’taking into account of others’; not for the sake of others, but for the purpose and based on clear and specific ruleset. 'Taking into account' can have a lot of different meanings, leading to more confusion (instead of solving it).

..on the other hand; If your proposal will reduce the tension behind it (puzzlement around responsibilities and duties of roles and members), go for it.
