TYPHOON ( pictured in this thread) and AKULA are 2 different submarines
Thread title and the video article ( in the original post) are incorrect
Actually, the thread title is correct.
Typhoon is the NATO reporting name for Project 941 Russian designation Akula, an SSBN.

Akula is the NATO reporting name for Project 971, an SSN.

The article (and thread title) is just giving both the Russian name and the NATO reporting name.
Although wikipedia is not always the best reference, it has a pretty good explanation:
"The NATO reporting name stems from the use of the word "typhoon" (тайфун) by Leonid Brezhnev in a 1974 speech while describing a new type of nuclear ballistic missile submarine."
"The Typhoon class was developed under Project 941 as the Russian Akula class (Акула), meaning shark. It is sometimes confused with other submarines, as Akula is the name NATO uses to designate the Russian Project 971 Shchuka-B (Щука-Б) class attack submarines."

and:
"Project 971 Щука-Б (Shchuka-B, 'Shchuka' meaning pike, NATO reporting name "Akula"), is a nuclear-powered attack submarine (SSN) first deployed by the Soviet Navy in 1986. The class is sometimes erroneously called the "Bars" class, after one of its members. Note that Akula ("shark") is the Soviet designation of the ballistic missile submarine class designated by NATO as the Typhoon class submarine. They are sometimes bitterly called "the Walker class," referring to John Anthony Walker, whose espionage data related to sonar detection was used to improve this submarine."
