Sorry for being ambigous.

<br>
Let's start over:<br>
The whole expression (<i>(...)(...)</i>) can be simplified
if the two partial expressions (inside the braces) differ
in just one negated variable.
<br><br>
If the whole expression can be simplified, then the result
is the first partial expression without the variable that
differs. (So have to pick first partial expression.)
<br><br>
That's why (in these two examples) one output is <i>(cb)</i>
and the other one is <i>(bc)</i>
