Do you mean two different crews in the Philly family had members operating in North Jersey?

Because North Jersey didn't become its own crew until the 1970s. Some sources have Caponigro becoming capo in the early 1970s but Fresolone wrote that Caponigro was bumped straight up from soldier to consigliere in 1978, at which point the North Jersey members began officially reporting to him. Prior to that they had been working for him in a de facto sense but actually belonged to John Simone's crew.

And even then, the Philly guys in North Jersey were one crew until Fresolone was briefly a captain in 1990. Then you had two captains in Newark - Fresolone in charge of Centorino, Cifelli, Olivieri and Praino, while Licata was in charge of DiNorscio, Napoli, Caprio, Capozzi, Sodano, Ricciardi, Bellina, Fusella and Attanasio.

The two-crews situation in Newark may have continued during the 1990s, with Licata and Blackie Napoli both reported to be capos for Stanfa in 1991. Then Napoli was taken down, and Licata and Sodano were observed going down to Philly together to meet with Stanfa until Sodano was locked up in 1992, at which point Licata continued going down to Philly alone until he was jailed in 1994.
Licata gets out in 1997, by which point Pete Caprio has been upped to capo after arranging the murder of his predecessor Sodano. But then in 1998 Licata is charged again with being a captain in the family.

So it's possible that in the 90s, they had 2 crews in North Jersey (Fresolone/ Licata, then Napoli/ Licata, then Sodano/ Licata and finally Caprio/ Licata) but I haven't read anything to suggest there was more than one Philly crew in Newark before then or that there was even an official Newark-based Philly crew before the 1970s.
