Tooltips in this game are often not telling you what exactly you have to expect from spell.
I was trying to understand what this ability actually do:
Veiled Strike -> Concealed Weapon
... blah-blah-blah. Passively increases stealthed movement speed by 25% while slotted.
OK, the first thing I thought of it will increase my sneaking speed, you know, when you just press ctrl. But Its not. Instead it increases your speed only while you under effect of Shadow Cloak . BUT its own tooltips says Gives player invisibility for 2.5 seconds.

OK. then invisibility and stealth is the same thing here right? Lets pretend that I did know it okay.
BUT here we have passive ability Master Assassin and what its tooltip says is Increases Weapon Damage while using Invisibility or Stealth by 5%. Successful crouched attacks stun for a longer duration.
So what it does exactly? Maybe stealth is actually sneak and invisibility is the thing Shadow Cloak does?
And we have khajiit's passive Stealthy - Improves Stealth radius by 1 meters. Increases damage done from while Stealthed by 3%. Where definitely it means sneak.

So Veiled Strike morph is bugged or tooltip is just not right?
