then if he wants he may state about himself: 'Hell is ended; animal wombs are ended; the state of the hungry shades is ended; states of deprivation, destitution, the bad bourns are ended! I am a stream-winner, steadfast, never again destined for states of woe, headed for self-awakening!'

"I am a stream-winner!", and as for people like Nyom Alexander, at least you can help them with frog-pills. Be aware that a fully awakened person neither lives nor could live in a household, other than the Noble Beggars.
As for a monk, it's not good to do so (toward laypeople) and if doing such as a deliberated lie it is even a reason to fall out of the community.
It may be good to add that a stream-enterer would seldom be able to teach and lead much and as most are still just a householder, give less inspiration for those having real faith. 
But it's a great achievement and a great place for mudita with such or sometimes for much karuna, like in Nyom Alexanders situation, not even knowing the Dhamma yet and believing to be awakened. Thats really much place of huge pity and the reality that beings are heirs of their actions, not really to be helped.
See a Noble Ones answer for more details; and keep such people high and protected without the need that they would need to tell.

There are many reasons one might do it here are examples from the canon;

  Then Sariputta the wanderer went to Moggallana the wanderer. Moggallana the wanderer saw him coming from afar and, on seeing him, said, "Bright are your faculties, my friend; pure your complexion, and clear. Could it be that you have attained the Deathless?"
"Yes
then if he wants he may state about himself:' Hell is ended; animal wombs are end; the department of state of the hungry shades is ended; state of deprivation, destitution, the bad bourn are end! I am a stream - achiever, steadfast, never again destine for states of suffering, headed for self - awakening!' 

 " I am a stream - winner! ", and as for people like Nyom Alexander, at least you can avail them with frog - pills. Be aware that a fully awakened person neither lives nor could live in a family, other than the Noble Beggars. 
 As for a monk, it's not good to do then (toward laypeople) and if doing such as a deliberated lie it is even a rationality to fall out of the residential district. 
 It may be good to total that a stream - enterer would seldom be able to teach and lead a lot and as most are still just a householder, give less inspiration for those having veridical faith. 
 But it's a great achievement and a great place for mudita with such or sometimes for much karuna, like in Nyom Alexanders situation, not even knowing the Dhamma yet and believing to be awakened. That s truly much place of huge pity and the world that being are successor of their actions, not really to be avail.
