$input-btn-* overrides doesn't work using SCSS

There are several $input-btn-* variables that are used by both $input-* and $btn-* counterparts like this:

$input-btn-focus-box-shadow:  0 0 0 $input-btn-focus-width $input-btn-focus-color !default;
$input-focus-box-shadow:      $input-btn-focus-box-shadow !default;
$btn-focus-box-shadow:        $input-btn-focus-box-shadow !default;

But, when I modify the value of the $-input-btn-* variables it doesn’t affect the $input-* nor the $btn-* counterpart.

I am not that familiar with SCSS, so I can’t see the cause, but this seriously add more complexity to the variables since I have to override all places the $input-btn-* variables are used.

Hmm ok, maybe @andresgalante or @mdo can confirm that

!default means you can override it. So you are not doing it properly.
