This, again, isn't a fact, it's an interpretation. Vegeta at the end of his fight with Goku has no sparks, and even though people claim he powered down to Super Saiyan, Goku was still a Super Saiyan 2 right up until Vegeta knocked him out. Even after he's knocked out and has no sparks, he's still a Super Saiyan 2 before he reverts to base.
The only official material that claims that sparks make the SS2 is the GT Perfect Files, which actually make a mistake in this claim (they say no-one in GT turned SS2 because they lacked sparks, yet we see Goku clearly transform into one) which really hurts their position on this.
It's funny, the people who say Gohan wasn't a Super Saiyan 2 sound
exactly like the GT Perfect Files do on the matter - "Gohan/Goku wasn't a Super Saiyan 2 because of the lack of sparks, despite him being a Super Saiyan 2 being confirmed by Daizenshuu 7/His fight with Rilld".
Unless you can find an official statement that sparks make the Super Saiyan 2, that applies to the manga and doesn't contradict itself, what you're saying is your interpretation.
