The regs. make no provisions for your situation. Common sense says to only punch it once because 1) you know it's the same fish and 2) WDFW doesn't treat released fish as the same one when they interpret the data of the turned in punch cards.

However..........

A release is a release so you have to record it. If a warden was in the bushes watching your every move(rare these days) and he saw you not punch your second release.....he'd nail you because you couldn't definitively prove it was the same fish.

Better to be safe and punch it!
