Normal Chests Side by side

Started out-fitting my first survival house with the very basic bed, chests, crafting table, furnace, and purely by mischance, as I wasn't standing directly in front of where I wanted to place a third chest, I placed a normal chest directly beside two other normal chests. I then repeated this action, and you can see I have 2 single chests beside double chests. These are not trapped chests as you can see from the snipping tool pic, they are all normal chests. I can't see anywhere in the patch notes which says the normally required interspersing of trapped/ordinary chests has been made redundant.
