Given he believed he was the lines ultimate culmination ( or something along those lines at the end of the Plagueis nove IIRC ) I don't see why not. It's not like either Tenebrous, Plagueis or Sidious really cared about the lines established by Bane tbh. They flout it throughout the entire Plagueis novel.
Like I said I don't believe he was training Dooku. I believe he taught him those techniques as a way to tie Dooku to him and maybe even to mislead the Jedi.

In any case, that just raises the question of why Sidious was training Dooku as a Sith even when Maul was around, regardless of whether Dooku was a Lord or not. [/B]
I think Sidious started cultivating Dooku as a useful idiot and dangled Darth-dom and training in front of him to get him to do what he wanted, specifically place the order for the Clone Army using the Jedi's authority.
When Maul got killed Sidious figured he might as well go with the flow and took Dooku as his apprentice.
I never really cared or paid much attention but IIRC ever since the movie(and the EU works that followed) came out there were inconsistencies on when exactly did Dooku leave, when was the order placed, when was Sifo Dyas killed, or whether it was Sifo Dyas that placed the order or Dooku assuming his identity.
Well, take note that a number of the quotes are character assumptions/perspectives, which would be limited. They wouldn't know everything. A number of them would have no idea that Dooku had a hand in it.
As I said, at least it was clear that Dooku never became Tyranus until after TPM, but this TCW retcon throws a spanner into the works.
