More-or-less true. He inherited a few of Jago’s plus buttons (close MK, crMK, etc) so he can string together a few frame traps and confirm some counter hits up close. (clMK counterhit into clMK xx reaction slide is very doable.) You can press clMK a few times and then go for an ambiguous jump forward crossup like Jago can. He also zones pretty well, and his divekick makes him difficult to anti-air so feel free to just do jump-ins on occasion.
Also, not plus frames per se, and not a safe frame trap unless you spend meter, but push kick (fwd+HK) cancels into dash, off which you have something like a 5-way mixup (DP in front or behind, throw, dive kicks on either side which can be surged to make safe, maybe even just end the dash into a low button?).
Finally, surge divekick may be -3, but your opponent probably isn’t pressing a button on frame 1 after it.
You know you can cancel any normal into axe kick (back+HK), right? -3 on block, staggers on hit, some normals combo into it.
