My reading is that this value is the actual max packet size used in the connection, it's just not clear from the explanation.  kInitialWindow and kMinimumWindow are also per-connection fields defined directly below.

There is one potential detail, which is if the MTU increases after the handshake, do the min CWND and Reno behavior change accordingly?  I think it's simpler to reason about them not changing, but I can see both arguments and in the end I don't think it'll matter that much.
