Dropping the third hit?

I’m terrible at Street Fighter, but when I’m bored I watch battles, Sakura is my favourite character. I was watching a Chris G vs Sako and whenever he hit his ex spin kick, (dont know names off top of my head) then went into the jumping attack, he would always not hit the 3rd one. Is there a reason for this and is it the best way to go?

It’s because 2 hits gives her much more mixup/setup potential, recovers faster when landing and doesnt put her in the corner. 3 hits has its uses though mostly against Bison but thats about it.

Thanks! I figured it was for the matchup (Evil Ryu for he wouldn’t be able to recover as fast and get off a shoryuken.)
