It's a combo you have to time obviously. If you press the next string too early your input can get eaten. But it's possible to input the 44 late enough to not get eaten, but soon enough for it to whiff anyway. Making this combo easier to mess up if you're freaking out or a newer player. Here's how to practice it and a deeper look at why this happens.
If you have any questions or if there's anything else you'd like me to cover with Skarlet that's troubling you just let me know!
