So if I may, I will summarize your response to the original question: "Anchoring single handed whilst hove to?" I interpret your response above to say: "It makes no sense to do that."
OK. You are entitled to your opinion.
Your definition of "hove to" seems to differ from mine. It wasn't practical to include an instrument reading in the video, but I assure you, the wind was directly abeam (90 degrees offset from the boat's heading). You may have studied sailing somewhere different than I, or you may not be accustomed to appearance of a boat with a full keel when hove to.
You are correct about my answer to the original question: "Does anyone have experience heaving to, going to the bow and dropping the anchor from there, crouched down behind the backed jib?" is that I have a lot of experience doing all four of these things, (heaving to, going to the bow, dropping the anchor, and couching behind a back-winded jib), and based on that experience, in my opinion it makes absolutely no sense to heave to in order to drop the anchor, especially when short handed for the reasons stated earlier.
My definition of "heaving-to" is the traditional one: i.e. Heaving to is when a vessel is at or nearly at rest approximately perpendicular to the wind, with the state of being hove-to achieved through the balancing of the set of the sails, and the helm. If you have a different definition, it might be helpful to explain how your definition differs.
Given that the telltales on boat in the video showed that the wind was well forward and that the bow wave showed near continuous forward motion, that boat would have more closely met the definition of fore-reaching, rather than the definition of being hove-to. There is nothing wrong with fore-reaching to drop a sail, in fact it works well since it keeps the sails more closely centered over the boat as it comes down.
When hove-to most boats 'cradle' which is to mean moving slightly forward and slightly aft and coming slightly towards the wind and slightly away from the wind as it does, but when hove-to and in keeping with the goal of being hove to, the wake will leave the boat nearly perpendicular to the boat.
While on the subject of definitions, similarly the boat in the video, (a Pearson Ariel or Commander) would more closely meet the definition of a long fin keel (using the definition of a fin keel that was in use at the time that the Ariel or Commander were designed, i.e. a keel that is has a bottom that less than half of the length of its sail plan) with attached rudder or by today's terms, a cut-way keel with raked rudder post rather than it being a full keel.
To illustrate, here is the keel on the Ariel:

Here is a full-keeled boat that I used to own:
Indian out of water Big
And yes I have hove-to in both full keel and cutaway keel boats and so I am very accustomed the appearance and feel of being hove to on both types of keels. With that in mind, I still respectfully suggest that that video is misnamed since the boat in question was not hove-to, and that anchoring either hove-to or fore-reaching makes no sense.
