Since 4 days that nobody was able to answer this question, so I did my research and I confirm that it is indeed the answer "1)"

1) All of the handles can be merged.


How the Magento layout merge works ?

1. When loading a theme, Magento reads the configuration of all the available modules, and checks which layout files should be loaded.

2. For each file, Magento tries to load it from your theme.
If it exists in your theme, it loads it and goes directly to step 4.

3. If the file doesn't exist in your theme, it tries to load it from the base/default theme.

4. Magento parses the XML files and merges them into one.

5. Magento looks for a local.xml file in your theme, and appends whatever is there, to the previously merged layout handles.

Hoping that everyone knows now.
