i'm no hero
agree that in play this is auto shove river
but...
villan is 15/11from utg, which hands open?
KJs is in his range (KJo i think not open from utg)
AK/AQ...but call raise with this flop?
AJ which is in his range (overfull)
77/JJ/AA he can play them in the same way
QQ/KK do not pay more river
2 combo call push river from behind
13 combo crush our hand
also if we esclude AJ combo which sometimes push turn (bad push IMO because Hero never call from behind), river we don't have the right equity for to make the push +EV
thus reflecting this fold is not so wrong...
i hate reply like +1, ship, LOL etc... w/o explanation
