Looping and nested sections

How should the following situation be handled:

...
tmpl_assign("foo", array(1, 2, 3));
...

...
{{section sec1}}
	...
	{{ $foo }}
	...
	{{section sec2}}
		...
		{{ $foo }}
		...
	{{/section}}
{{/section}}


Should only sec1 loop through the values of $foo and sec2 just uses the
current iteration's value, or should the looping be restarted for sec2?
It seems that the first solution would be more intuitive. Comments?
