Some Guy like filho do Judo and Bjj but claim themself or are known as Jiujitsu guy.
Other like Leite do both, but claim themself as Judoka.
I've havent see filho in bjj comp , so I'll use Jacare and Leite as sample.
Jacare stand up is Judo but his groundwork is pure Bjj. I'vent seen a Judoka fight like Jacarè Did. It's not about quality, but about Style of Ground work.
U don't see any judo guy doing spider guard for examples.
Leite Stand up is judo off course, but also his Groundwork is the groundwork I've seen done in each judo competition. He use Yokosankaku, He use the typical Cuban Okuri eri jime (a variation of clock choke), he use long Osaekomi (pin).
He know how to defend Bjj guard work for sure, cause he train with bjj guy a lot, but also a lot of Judoka fought or train in sambo or wrestling but are still judoka.
If a wrestler compete in Judo (and train with judoka to do it) and win his match with Double Leg Takedown and Wrestling turnover on the ground, He is a wrestler in Judo. Cause he use wrestling in his match. Sure that move maybe exist in Judo too, and Sure he train with judokas , but the Style IS wrestling (cause nobody except ex-wrestler use it)
Leite fight different from any other Bjj guy i've seen, but just as the typical Judoka with a very good newaza.
This is the video about the Cuban Okuri eri jime I was talking about
