Yes, I believe your interpretation is correct in that this section really is dealing with those who have indicated a desire to present a statement at the board. The intention of the government's amendment here is really one of consistency with the existing CCRA language.
The government amended the CCRA in 2012 and enshrined the entitlement of victims to participate in parole hearings and make statements. The language that exists right now says it's by means deemed appropriate by the board. A victim may make a statement, they can read their statement, or they can participate through audio recording or teleconference.
The amendment here is really just to ensure consistency with what's already in the act. It's up to the victim to indicate the manner in which they want to participate, and every effort is made by the board to accommodate that.
