Well factfile isn't canon, but is fine for discussing Legends or Canon/Legends composite.
Dave saying Sidious is untouchable though could be referring to the fact that Sidious could have TK stomped them anytime he wanted. In fact we see that at the beginning of the fight and regarding the end of the fight he says something like "once Sidious has had enough he puts his Lightsabers away and Maul's Maul".
The "toying" on the official website could also be referring to Sidious TK stomping Maul at the end.
So these statements are not necessarily blanket statements that apply literally for every part of the fight.
Btw in the episode featurette on the official site, Filoni also said that Savage put up a better fight against Sidious than the 3 Council members. That wouldn't make any sense if Sidious never tried at all against the brothers.
On the ther hand you're probably right, because once someone is holding back it's impossible to know how much and for how long. Just saying those statements by Filoni and the website aren't as black and white as you suggest.
