Yes, it can be that. We do this as a way of knowing the TM and if one has the "right" to move on. Since we often use this as a deload week OR a test week, it kind of depends on what you use it for. Most of the time we do it for a set amount of reps: 5 being the usual goal for most lifts.
As you know, after you do the program for awhile, the TM becomes less relevant to your actual max. The most progress in our weight room comes from people using at the most, 85% TM. Especially once they've been training for awhile and know how to push PR sets and know bar speed for their supplemental work.
It's a nice balance between stupid and smart.
