The time length of ults are usually to prevent overusage because there is nothing else holding it back other than occassionally mana.

The idea is that Yasuo's ult can be up on the offchance he has the small window to use it through a random knockup. Ideally his ult is whenever someone gets airborne. The longer the CD the less likely he will be able to chain with his allies.

Although it's not THAT hard to get his own personal knockup off you just can't get it off as easily in a straight fight.
