This is great and your way works well, but I just wanted to say one thing: for me, personally, I find a lot more success getting this combo down consistently when I delay the b3 as much as possible. When the opponent does that weird bounce that's awfully low to the ground when you delay the b3, it's an extremely easy connect into the 32 xx 4332 1+3. Just a personal preference, but it works consistently for me.
On that "it works for me" note, for those having trouble with the trait coming out consistently: I tend to think in terms of patterns, so my pattern for his trait is 4 33 (slight pause) 2 1+3. I basically double tap the 3, give a minor pause, then double tap the next two in the string. I haven't dropped a trait ender since doing it that way. I imagine most RH mains have their own way of getting that consistently, but I've seen more than one post mention how inconsistent his trait can be, so just trying to give anybody with trouble an alternative option to try.
