The whole thing is kinda different, it launches from a tube that stays on the ground whereas every other ICBM I've seen the entire thing is designed to go up. Seems like the first blast of the triple firing happens when it clears the tube?
Guesswork: Maybe they're launching from the top of tube to avoid launch pad damage? Elevated ignition? ICBMs of this size usually launch from a silo whereas this launches from a mobile launching device that will always have ground beneath it.
Remember when the SpaceX rocket absolutely obliterated a launchpad?

Yeah that makes sense
So the first blast is the thing clearing the tube, the second one maybe a charge meant to ignite the solid booster and then last the burn
