q about authlogic

hi, this is part of the standard UserSession Code:

def create
@user_session = UserSession.new(params[:user_session])
@user_session.save do |result|
if result
flash[:notice] = “Successfully logged in.”

p “----------A-------------------”
p @user_session.inspect

p “-----------B------------------”
p current_user.inspect


LOG
B: “nil”

but, i do have this in the app-controller:
def current_user_session
return @current_user_session if defined?(@current_user_session)
@current_user_session = UserSession.find
end

def current_user
  return @current_user if defined?(@current_user)
  @current_user = current_user_session && current_user_session.record
end

so , why cant i access current_user- record (in A)?

thx
