Examples don't match the usage rule

Question

The usage rule says "You can also use aller à + person to ask/say that [someone] is fine with [something], i.e. that something suits you:" but neither of the examples use à.

Ça vous va ?

Ça lui va ?

It's confusing.

Accepted Answer

Well, they actually do but it is hidden. I can understand why you'd be confused.
Ça va à Marie. -- Ça lui va.
When replacing the indirect object à Marie with the pronoun lui, the à disappears, as it is implicit in the indirect object pronoun.

Answer

Oh, good to know! It would be helpful if they would mention that or add a link to a lesson for it (if one exists) because I don't think I've encountered anything mentioning that before. At least, there should be an example that actually includes the à, as yours does. Thanks, once again, for your help!
