Confused about `one_of` vs `attribute_equals`

Still messing around and encountered a confusing behavior with validations. I have a

:verify

:verify

action on a resource, which I only want to run on resources which have

:role

:role

set to

:unverified

:unverified

The below works as expected (produces valid/invalid changesets as expected):

    update :verify do #custom action to verify an unverified user
      validate attribute_equals(:role, :unverified) #only verify unverified users
      change set_attribute(:role, :verified)
      accept []
    end

    update :verify do #custom action to verify an unverified user
      validate attribute_equals(:role, :unverified) #only verify unverified users
      change set_attribute(:role, :verified)
      accept []
    end

What confuses me is that the below version using

one_of

one_of

instead of

attribute_equals

attribute_equals

seems to me like it should do the same thing, but it never seems to produce an invalid changeset:

    update :verify do #custom action to verify an unverified user
      validate one_of(:role, [:unverified]) #only verify unverified users
      change set_attribute(:role, :verified)
      accept []
    end

    update :verify do #custom action to verify an unverified user
      validate one_of(:role, [:unverified]) #only verify unverified users
      change set_attribute(:role, :verified)
      accept []
    end

Can someone point out what I am misunderstanding?
