Me too all the blood rushed to my other head!
They bothered me in the way that staring at that many rolls of life savers always does. Mad I can't eat it! Wait What???
I honestly think that it just depends on the goal of training or even that specific set. However with you working out alone i would definitely agree with the statements below when using free weight compound movements. However the exercises where this was listed there really is no more danger in doing a partial or even multiple partial at the end of the set so long as you keep good form with the partial. Most were single joint very easy to bail on exercises where stopping at any point in the ROM had no more danger than a full ROM if not actually being safer. The key there being controlled. IE stop when you get to any point that requires any adjustment of form. So with those, and the lat pull down as well it is VERY easy to stop at a safe point without risking injury. Just don't try to push through and allow yourself to lose form, either shorten the range or abandon the set.
John Meadows is a big proponent of controlled partial reps, I love controlled partial reps and often have to resort to them when training if my problem areas are bothering me. Muscles undurstand tension, and you can get massively high % recruitment from an intense partials. My ortho begged me for years to start training my heavier movements with partials explaining the difference in fiber recruitment VS safety. Bottom line fiber recruitment under sufficient weight is just has high and often higher in the strongest, or safest portion of the ROM compared to FULL ROM due to the difference in weight able to be used and if you increase TUT with slower negatives then you do not lose TUT due to shorter ROM. So the benefits actually outweigh the risks their. Most people will scream FULL ROM from the mountain tops but most top level body builders do mostly partial ROM in the safest area of the ROM mostly in the middle 3/5s of the ROM. On top of that partials also keep tension on the muscle between reps.

John Meadows on partials
General Youtuber - showing examples of pros lifting and them discussing the partials.
Really just discussing and sharing some different thoughts, aspects, and approaches here since you asked for thoughts on the matter.
That being said I think you are following Bob's programming here, or his suggestions and there are absolutely nothing wrong with them either. Bob knows his stuff, and this training methodology works for certain. Both options address that safety and form is of great importance. Just different ways to approach progressive overload and at different intensity levels. So many ways to skin a cat and they are all correct as long as you have a skinless cat at the end...
I will say there is something to be said for a oh lets call it a ROM drop set since I don't know if there is a name for it. I guess it could be considered a mechanical drop set except instead of changing to more advantageous angles to continue the set you work through a progressively shorter ROM until form failure at whatever predetermined ROM you are willing to go down too.[/QUOTE]
I’ve definitely seen this to be very true firsthand. Training at different gyms with pro card BB’ing monsters the partial reps seem tried and true for that discipline. Like you said, depends on your training goal.
