It's a very basic HTML/HTTP idiom::

<form method="get" action="previous_url" tal:condition="previous" 
tal:attributes="action request/URL0">
  <input type="hidden" name="start:int" value="somedefault" 
tal:attributes="value previous/first" />
  <input type="submit" name="Submit" value="previous" />
</form>

One could also do the slightly more compact but less clever::

<form method="get" action="previous_url" tal:condition="previous"
  tal:attributes="action 
string:${request/URL0}?start:int=${previous/first}">
  <input type="submit" name="Submit" value="previous" />
</form>
