Why this pattern cannot have any puzzle with hidden singles (ER=1.2, 1.5) ?

As adding any given to a puzzle solvable using hidden singles gives a puzzle solvable with hidden singles, I'd say because this pattern cannot have any puzzle solvable with hidden singles:

Code: Select all: x x x | . . . | x x x x x x | . . . | x x x x x x | . . . | x x x - - - + - - - + - - - . . . | x x x | . . . . . . | x x x | . . . . . . | x x x | . . . - - - + - - - + - - - x x x | . . . | x x x x x x | . . . | x x x x x x | . . . | x x x

A quick inspection shows that there is no row single, column single, nor box single.

How about this pattern ?

in row 4, then digit 1 at b,c.
in row 5, then digit 1 at a,c.
in row 6, then digit 1 at a,b.
So digit 1 cannot have hidden singles in col 1.
Same as digits 2,3,4,5,6,7,8,9.

Code: Select all: x x x | x x x | x x x x 1 x | x x x | x x x x x x | x x x | x x x - - - + - - - + - - - a . . | x x x | . . . b . . | x x x | . . . c . . | x x x | . . . - - - + - - - + - - - x x x | x x x | x x x x x 1 | x x x | x x x x x x | x x x | x x x
