Well yeah but we are dealing with a sensitive topic here, of which the details are ambiguous, a layman, or even an informed SW enthusiast, could easily have overlooked the revelations in this episode.
Perhaps.
And I saw that, but again Sith =/= Sith Lord. Venamis is a Sith name as well, so is Bane. It represents their (and his) affiliation with the Sith. I mean, its not just a nickname, clearly.
Tenebrous was training Venamis to kill and replace Plagueis, and Bane was a Lord by the time he created the Rule of Two.
My question was mostly about why Dooku had the name Tyranus already, but also what the implications of that were. Sidious inducting Dooku as a Sith is a violation of the Rule of Two, just as Tenebrous training Venamis was. If you're comparing Tyranus to Venamis, that would mean that you think Sidious wanted Dooku to replace Maul, which doesn't make much sense as far as potential goes.
Although, as Ares said, Sidious may have wanted Dooku to replace Maul anyway because of his charismatic ability. Personally, I find that that theory only operates under the assumption that Sheev was already aware of Anakin and had set his sights on him, so he realized that Maul was ultimately expendable (which is stated on the SW website as well). Dooku was also expendable, of course, but at least he would've been able to initiate the Clone Wars and serve as the public face of the Sith. And since Sidious was planning for Anakin all along, it really wouldn't matter what Maul's potential was since he'd never be able to attain it before Anakin grew old enough to be indoctrinated into the Sith Order, at which point he'd just be a better version of Maul.
In other words, it's possible that Sidious found them both expendable by this point but considered Dooku more useful to his plans until he could get Anakin to become his apprentice - hence he began cultivating Dooku for apprenticeship over Maul.
That's for Canon. In Legends, he foresaw Maul's demise on Naboo according to Jedi vs Sith: The Essential Guide to the Force, which means that he probably trained Dooku to become Maul's inevitable replacement as the Sith apprentice.
There is also context to consider as well, by the point of this discovery, Tyranus was Dooku's Sith name in every sense of the word.
I'm pretty sure the quote means that Tyranus was a Sith name from the get go, not just an alias adopted by the Count which ended up becoming a Sith name.
