To answer your question, the jutsu itself comes from a game, and it was shown to actually be a stream. So I think when it is said shorter, it means the reach of the fire stream is shorter. But, judging by the description, it actually exists in both forms, stream and projectile, just smaller in size and reach.
Everything else was quite flawless, shall we continue?
I create a clone which stands before you in battle position.
Now, you will grab into your ninja pouch and take a bunch of shuriken out. Thrown them with very correct precision, at your enemy. What I want you to do next, is exhale a fire infusing chakra to them, which will ignite all the shuriken separately. The shuriken now will travel towards the enemy, while they are in fire, and if they hit, they will continue the burn the target. It is especially better if you boost their speed with wind, or try to limit their vision greatly. The fire infused chakra has a lot of potential in the Ninja World. Use it wisely...on my clone.

This technique is a rather unique one, so we will learn another aspect from fire release entirely. As you most likely learned from Akasha-Sensei, fire release can be in different shapes them being flames, ignitable gas, and ash. You will release from your mouth, after performing 4 handseals, huge amounts of ash. Since the ash is fairly light, it will seemingly float towards the enemy, but as soon as it touches, it created almost 3rd degree burns. Now, this technique also has a very nice specialty, and it is as soon as you click your teeth, it will ignite into a very violent explosion. You can also use wind along with it, to push it forward at higher speeds, careful when you use it, wind can push it back as well. Use it on my clone.(Katon: Haisekishō) - Fire Release: Ash Pile Burning

Description: The user spews superheated ash from their mouth after performing four handseals. The ash is hot enough to cause third-degree burns on the victim. Because it's composed entirely of ash, it stays in the air around the victim like a cloud. If the user clicks his teeth, the stagnant ash will ignite, creating a violent explosion.

Alright, another fairly nice technique, and often used as a prior to the ultimate lightning technique. You will charge fire chakra inside your body and perform one handseal. Then, you will similar to fireball technique point your finger close to your mouth and then release the flames. You will release 5 fairly large projectiles, and shape them into dragon heads. Most of the time, they are targeted towards the clouds in a supplementary fashion, but the technique itself packs a punch too. So, use it against my clone and-Random very large chicken appears. You know what...I whisper in your ear. Use it against that thing there.(Katon: Gōryūka no Jutsu) - Fire Release: Great Dragon Fire Technique

Description: The user unleashes a volley of shuriken with one hand, while at the same time exhaling fire-infused chakra onto them in order to increase the weapons' destructive potential by making them capable of inflicting severe burns upon direct contact with either the intended victim or any other object caught within their trajectories. Due to the chakra-based nature of the flames that surround them, the shuriken will continue to burn after impact, regardless of the flammability of the object that they ultimately collide with.
