'Wix toolset - hide/show controls - why both are needed?

I saw many examples like this:

<Control Id="contorlId" Type="CheckBox" property="PROP1" CheckBoxValue="1">
       <Condition Action="hide">A</Condition>
       <Condition Action="show">NOT A</Condition>
</Control>

Why is it required to set both conditions? (In most/all cases the 'hide' condition is the NOT of the 'show' condition.

If the condition is more complex, such as the following:

<Control Id="contorlId" Type="CheckBox" property="PROP1" CheckBoxValue="1">
       <Condition Action="hide">    A AND B AND C AND D AND E</Condition>
       <Condition Action="show">NOT(A AND B AND C AND D AND E)</Condition>
</Control>

this redundancy can easily lead to bugs.

Is there a way to write this without having to specify both 'show' and 'hide' conditions, but keeping the same functionality?

Thanks
