Pass Block through multiple Templates - twig

Question

I am trying to set up some common templates, that I want to use throughout my site.
Starting with a template in order to render Users. I have devided this into two different subtemplates:
users.html.twig (Template in order to show a table of Users)
user.html.twig (Template to render a single User)
Depending on the Controller this subtemplates are "included" I may want to add some buttons for each user.
Lets assume I have an action where I can search for users. This Action has the template search.html.twig
Now I want to include within my search.html.twig the users.html.twig which itself includes user.html.twig. The tricky part is, I want to define in search.html.twig a single block that is rendered in user.html.twig. I tried it with embed, but unfortunately it renders nothing:
search.html.twig
{% embed 'StregoUserBundle:Entity:users.html.twig' with {'users': results, 'perRow' : 3} %}
{% block user_additional %}
TOOOOOOOOOOOOP
{% endblock user_additional %}
{% endembed %}
users.html.twig
{% block user_table %}
{% for user in users %}
<div >
{% embed 'StregoUserBundle:Entity:user.html.twig' with {'user': user} %}
{% block user_additional %}
{{ parent()}}
{% endblock user_additional %}
{% endembed %}
</div>
{% endfor %}
{% endblock user_table %}
user.html.twig
{% block single_user %}
<div class="people-list">
<a href="{{ path('profile_show', { 'username': user.username }) }}">
<img src="{{ user.profilePic | imagine_filter('profile_thumb') }}" alt="{{ user.username }}" class="img-polaroid">
</a>
<h3>{{ user.username }}</h3>
<h3><small>{{ user.firstName }} {{ user.lastName }}</small></h3>
{% block user_additional %}
{% endblock user_additional %}
</div>
{% endblock single_user %}
I have tried several combinations of {{ block('XXX')}}, includes, embed, use etc... but did not find a solution.
