Deload is about workload even if weight per lift is higher the total is a lot less lifts.
Think tonnage 100x5x5= 2500lbs while 110x3x3= 990lbs
There really aren't 4 weeks of loading, there are 4 weeks of progression maybe more for someone newer or starting lighter. Probably 2 weeks of peak loading and really the way most guys set it up maybe less. Not many people can tolerate 3 weeks of peak loading which is what that 3:1 is getting at i.e. a lifter with all lifts already in shape.
Anyway the 2nd half training 3x a week with records in 8/9 is really a peaking program based on 3s not pure deload. For pure deload run 2x a week (just longer for a basic peak). So you could run 4 weeks, 2 weeks of deload or less if needed and then step back into 3 hard weeks of volume phase and see how you tolerate it. Fatigue is personal and accumulates according to what you do not just because you have 3 weeks on a time clock.
