People might assume this is an AP stomp, as Orange Piccolo was capable of holding his own against Cell Max, who was stated to be powerful enough in his complete state that not even Broly would've been able to defeat him. However, he was released prematurely, which I believe impacted both his power level and fighting ability. In addition to that, Orange Piccolo was only able to fight against Cell Max after his weak spot had been targeted by Gotenks and after he'd been critically injured by Gamma 2's self-destruct, with Piccolo later admitting that they would've never been able to defeat Cell Max were he not weakened from the self-destruct. When they fought, Orange Piccolo was dominated by Cell Max in a matter of minutes, so Orange Piccolo was notably inferior.
Golden Frieza was capable of holding his own against Super Saiyan Broly for an entire hour, and despite eventually being defeated, the novel states that his punches could stagger Broly and force him to dodge. Super Saiyan Blue Goku and Vegeta working together were barely able to hold their own against Super Saiyan Broly and retreated after less than a minute. So my point is that the difference in power between them shouldn't be too large, even if Orange Piccolo is indeed stronger than Golden Frieza.
