I think that quote is related more to high frequency/high intensity work, similar to daily squatting. It seems like people only need a few days off to hit a max since they don't accumulate as much fatigue with that type of training. What you did is high frequency/high volume so the week off will help remove a higher amount of fatigue accumulation and you will perform better with more recovery time.
It doesn't really matter if you hit a max or not because you put in the work and built some muscle from all that volume. After a week (regardless of whether you hit a 1RM or not), move on to a program with lower frequency/volume work and allow your body time to recover. Add a conservative amount to your training max and don't get greedy or you won't allow yourself time to recover and you'll go backwards. Slowly ramp up intensity and try not to touch 90+% within 2-3 weeks of hitting your 1RM. Take a break from intensity during your volume phase and take a break from volume during your intensity phase.
