When one striker has a significant reach advantage the general principle is to let him or her go first then you counter, you work off what he or she gives you. Maryna was going first, she was moving forward and throwing volume but Dynamite was just moving sideways all the time and not really engaging. If she did engage she lunged in, threw one punch then got TF back out again and kept moving and she is compact, athletic and explosive and moves fast, there was no sense in giving her what she wanted and coming in careless out of stance and getting caught.
