I'm not sure I understand what you're trying to do.

Is this what you're doing (semi-pseudocode)?

def foo():
    context1 = SekizaiContext()
    output = render_to_string('template1.html', context1)
    context2 = SekizaiContext({
        'output': output
    })
    return render_to_string('tempalte2.html', context2)

{# template1.html #}
{% addtoblock "css" %}hoge{% endaddtoblock %}

{# template2.html #}
{% render_block "css" %}
{{ output|safe }}

Close..
Difference: Imagine that foo being a template tag that does only use (render) template1.

Example:

@register.simple_tag(takes_context=True)
def label(context, label=None, **kwargs):
    label = label or context.get('label', {})
    label_context = label
    label_context.update(kwargs)
    label_template = 'atoms/label.html'
    return render_to_string(label_template, context=label_context)

So.. the difference is that label (template tag) only renders its template.
And I call the template tag in my main template somewhere.
The mein sekizai block tags are in the main template.

Does it make sense now?

sekizai cannot work if you isolate the context. You can however manually pass it:

from sekizai.helpers import get_varname

@register.simple_tag(takes_context=True)
def label(context, label=None, **kwargs):
    label = label or context.get('label', {})
    label_context = label
    label_context.update(kwargs)
    label_context[get_varname()] = context[get_varname()] # inherit sekizai context
    label_template = 'atoms/label.html'
    return render_to_string(label_template, context=label_context)
