Read the actual clauses.
It specifically says "VFL/AFL".
These are (since 1996) two different competitions.
The wording does NOT refer to a previous incarnation of the AFL.
The "VFL seconds" does not exist. It was previously the "Development League" and IIIRC has now ceased.
Despite what you or anyone may think wording in the Constitution means, it is read in an absolutely literal sense. I refer you to the current Citizenship "crisis" at the top of Australian politics.
Former VFL premiership players involved in a single win are being awarded Life Memberships, within the Boards right to award them. http://www.richmondfc.com.au/news/2017-08-24/life-honour-for-wa-tigers
The inclusion of VFL is thus redundant in a clause being changed in 2017, unless the intent is to reward future VFL players.
I note you have not mentioned the DELETION of the clause rewarding 100 games players.
Do you believe that players like Rioli, Free, Richardson, Knights and Deledio are not ENTITLED to Life Membership but only at the DISCRETION of the board?
