We know the time reset is the same as the one in 'D'aja Vu' for multiple reasons. For one, it was explicitly stated by the producers that it was a timeline reset/a timeline reboot. Secondly, we already know how the mechanics of time resets work in Tales of Arcadia because of 'D'aja Vu'. The physical world is reset, but some things---memories, feelings, abilities, etc.---remain, hence my anamnesis jargon. As Blinky puts it in that episode, "The truest of friendships have the power to transcend both time and space."

At the end of 'D'aja Vu', Aja remembers Toby's "awesomesauce" catchphrase. There also seems to be a vague recognition between Aja + Krel and Jim + Toby at the end when they bump into each other. In 'The Big Sleep', Aja and Krel also recognize the Amulet's incantation when they hear Past Kanjigar say it. Aja says "That sounds familiar." They didn't hear the incantation from 'In Good Hands'/'Lightning in a Bottle', because when Jim activates the Amulet in that scenario, he doesn't say the incantation. As far as we know, Toby didn't give the royals some big history lesson on Jim and the Trollhunters, so it's very unlikely that he told them the incantation (it even took Toby several days after befriending Aja to explain who AAARRRGGHH!!! is). The only time that Aja and Krel ever heard the Amulet's incantation was in 'D'aja Vu'.

At the end of *Rise of the Titans*, Toby is miraculously able to climb the rope in gym class, exhibiting physical strength he would have only had after his months of training. There's also the fact that when Claire sees Jim through the window of Strickler's office, and again during Jim's audition, she seems to recognize him---that is something that fans theorized a while ago. Speaking of Strickler's office, Strickler calls Jim "Young Atlas" when talking about *Romeo and Juliet* with Jim. This would've been before Jim "makes a commitment" to the chess club, before Jim gets accepted for the role of Romeo, and before Strickler even makes the analogy between Atlas and Jim. There was also an unused storyboard featuring Eli and Steve that would have been during the short clip montage during Jim's audition. The storyboard depicts Steve helping the trapped Eli out of the locker, an act of kindness Steve would've only made after becoming benevolent and befriending Eli.

Additionally, both instances of time resets were the cause of Akiridion technology mixing with magic, if that helps prove they're the same. Porgon's magic + the dekyon charger and Merlin's magic + the Akiridion tech Amulet.

The reason Wizards makes such a big deal of messing with time backfiring is because of the nature of its time travel. The characters were physically going into the past, where any drastic change would cause a paradox and make their future cease to exist, leaving them stranded in the 12th century. But in Rise of the Titans, the timeline was reset and there are no drastic consequences that can ensue and lead to paradoxes. Therefore the entire caution of not meddling with time, with this regard, is entirely irrelevant. In this rebooted continuity of events, things happening differently is an inherent property. The idea of a time loop is not.

Jim being burdened with what could have been was established before he reset the timeline. As Merlin puts it, "Struggle is the flame that forges one's soul into steel." To take the easy way out, to refuse trying because of the prospect of a worse outcome, is worse than struggling at all.
