Magento 1.9 layout update order/inheritance

Did Magento change something with how the layout updates are merged in 1.9? I recently started working with 1.9.1.0 and I noticed that one of the blocks on the right side bar was duplicated. This block is added by a 3rd party module that stores its theme files in default/default. I had added code in my local.xml to unset the child and then re-add it so it appears at the bottom of the column. This used to work in 1.5.0.1 but does not work in 1.9.1.0. Instead, I was forced to remove the block completely using <remove name=...> and then add it back in using a different name. It's a work-around I'm ok with, but is this supposed to be happening?

3rd party module's layout update:

<default>
    <reference name="right">
        <block type="adjreminder/review" name="right.adjreminder" after="cart_sidebar" template="adjreminder/review.phtml" />
    </reference>
</default>

My local.xml:

<default>
    <reference name="right">
        <action method="unsetChild">
            <name>right.adjreminder</name>
        </action>
        ...
        <block type="adjreminder/review" name="right.adjreminder" after="cart_sidebar" template="adjreminder/review.phtml" />
    </reference>
</default>

This did not move the block but instead created a second copy. The unsetChild wasn't doing anything. The only way to fix it was for me to put this in my local.xml:

<default>
    <remove name="right.adjreminder" />

    <reference name="right">
        <block type="adjreminder/review" name="right.adjreminder" after="cart_sidebar" template="adjreminder/review.phtml" />
    </reference>
</default>

The <remove> directive does not remove blocks, but instead sets a flag to ignore block rendering of itself and all of it's children. If you wish to relocate a block, you need to use the <action> directive with the method of insert or append.

<reference name="right">
    <action method="unsetChild">
        <name>right.adjreminder</name>
    </action>

    <action method="insert">
        <name>right.adjreminder</name>
    </action>
</reference>

These action methods will use the current block instance instead of creating a new block instance. The action method insert will place it at the top of the list of children, while append will place it at the bottom.
