It does not literally grant greater invisibility but it does not end when you make an attack

Things do only what they say they do, and the Fade Away option doesn't say that it ends when making an attack. However you've forgotten a significant part of the feature:

You can use a bonus action to magically become invisible, along with any equipment you are wearing or carrying, until the start of your next turn.

 

Once you use this feature, you can’t use it again until you finish a short or long rest.

Compare this to the invisibility spell:

A creature you touch becomes invisible until the spell ends. Anything the target is wearing or carrying is invisible as long as it is on the target's person. The spell ends for a target that attacks or casts a spell [...]

You only use Fade Away once per rest which makes it far from game-breaking. It also lasts only one turn, unlike greater invisibility. Also keep in mind that this is a 10th level feature so it isn't coming into play until much further along character advancement.
