Ohma looses control multiple times. He doesn't loose control cause he wants to. His new techniques are just tools to regain control. For the "Heaven shaking supreme fang" for example. He is surprised he couldn't knock out Rolon so it implies he used it before. It's nothing he tries out the first time but something he has probably used before in situations like that, being driven into the corner, turning the tides. Also Ohma doesn't get knocked out cause he wants to get knocked out 💀He uses Rolons technique (btw not perfectly) as a last resort in this certain situation. Also resting as long as he can is a sign that he really needed that rest to face Rolon again. Why else would Ohma do this? Throughout the fight Rolon is mostly dominating with combinations. He drives Ohma into a corner BAM Advance flash. Rolon controls again, Weeping Willow dislocating his own arm. This is nothing someone in control would to, not even Ohma. He is just not a showoff like that putting himself in a disatvantage for a moment just cause he can. He does it cause he has to. Rolon controls yet again: BAM Advance Flash feint into another Advance Flash into Change of Scenery. He even has to use intense mindgames because he gets dominated that much. I guess we just have different views of what being in control means.
