I think it was just too far away to see the multiple nascent contrails. Positive of it.
Contrails can vary. It is all down to conditions. Some partially form, some disperse and some persist. There is also perspective to take into account and distance. The aircraft is moving away from the helicopter camera. People are still filming these ‘missiles’ being launched off California. See aircraft contrails from California back in December 2009.

Retired US Navy Admiral John Stufflebeem has provided an excellent on camera (Fox News) analysis of why he is confident that it was an aircraft.
