no
it's more like this
let's say a ssj has a strength of 5000 and a speed of 5000
and a ssj2 has a strength of 10000 and a speed of 10000
and a ussj would have a strength of 7500 and a speed of 2500
===========================================
super sayian(level 1)
ultra
super sayian(level 1)
super sayian (level 2)
it's like when u have a car, let's say a ferari f40, and u sacrefise weight to make it faste, it's still a ferari f40 but with different stats, but when u go ssj2 it will be a ferari f50.
============================================
ssj: "gold" hair, a bit more bulky
when u go ussj, ur high gets VERY spikey and u won't have pupils, and u will be a LOT bulkyer.
ssj2: less bulky again, but stronger then a ussj, and about two times as fast as a ssj.
===========================================
needed for ssj transformation: power and emotion
ussj: only power is needed
ssj2: power and emotion
now u can c why it isn't a ssj2, yet.
============================================
ussj is just a huge ssj
, it's also called:
Ultimate Super Saiyan (Super Saiyan stage 3)
while assj is stage 2; they DO ascend, but it's a ssj form and not a ssj2 form
