There are more ways of deloading than dropping down to two workouts per week.
My own way of judging when loading is happening is that the sets and reps become more a matter of willpower than of strength. Whether you get loaded this week is mostly a matter of how hard you pushed yourself last week to make new 3x3 and 1x3 PRs and how hard you push this week. You might even finish the week not loaded in which case you have the choice of going to a tenth week or diving sraight back into a fresh week 1 and new program.
Assuming you do finish this week loaded, then it makes sense to take a recovery week. The essence of any recovery week is that you aren't working as hard as before it. That might involve dropping down to doubles rather than triples or it might involve dropping the weights down to 50% and doing some speed work.
Personally, I like to take a chance to work on some exercises I've missed out on for a while. Maybe do some front squats or incline DB work and a bit of arm work, which I tend to neglect usually. Maybe take a chance to work on some cleans. You get the idea.
Like madcow says, it entirely depends on how deeply you're into loading from the intensity phase and how long you, personally, take to recover from these last two weeks of the program. Given the enhanced recovery from being on a cycle, I'd expect that one week of lighter 8-10 rep work and some fresh exercises over two or three days as you see fit would leave you ready to dive straight back into a fresh run.
