Yes. It is set on call.

Eg. if you have tamplate foo containing:
<span style="{{{bodystyle|}}};{{{style|}}}">{{{1}}}</span>


You could call it as:
{{foo|Hello World!|style=color: blue|bodystyle=background-color: red}}


And the result will be:

<span style="background-color: red; color: blue">Hello World!</span>
