The extent of Kas'im's mastery, how long it took him to originally master every form, how long he had spent perfecting them, as well as the fact that he was the greatest swordsman in the Galaxy, and possibly ever.
While it is not totally beyond the realms of possibility that Kas'im had informed Bane of the extents of his training, and that Bane may have simply been vaguely assuming the latter about Kas'im's status as a swordsman, it's the fact that the descriptions encompass a form that Bane wasn't even aware that Kas'im was even slightly proficient in, until a few moments ago, that renders it something that Bane absolutely would have not been in a position to know.
That he had been winning the duel all the way until Kas'im switched to Jar'Kai, as well as the fact that the descriptions of Kas'im's mastery of the lightsaber were being used as the reason for Bane being unable to defeat him would indicate that the descriptions took into account Kas'im's mastery of Jar'Kai, a form Bane didn't even know that Kas'im was even a practitioner of until moments ago, affirming the idea that he clearly would not have been in a position to recall the extents of Kas'im's mastery in such detail.
To expand on that slightly; one of the prime reasons given for Bane's early dominance over Kas'im was that he had memorised all of Kas'im's moves and was able to recognise and counter every one of them.
But then when Kas'im uses a form that Bane hadn't even been aware that Kas'im was slightly proficient in, those descriptions regarding his mastery are largely attributed to the reason he was now on the losing end of their engagement (which we know was because Kas'im switched to Jar'Kai, a form Bane was unfamiliar with), which would indicate that those descriptions were taking into account Kas'im's mastery of Jar'kai (and not simply Kas'im's mastery of the forms that Bane did know about and could counter perfectly - something that was attributed to his early dominance), a form Bane hadn't even known that Kas'im could use, let alone being able to recall his studies under the form [even when grouped together with those that Bane knew, the detail would correspond with all of the forms, including Jar'Kai].
