List item created through workflow does not start "new item" workflow

I have got a list with two workflows:

1. One workflow executes every time a new item is created and sets a column to a particular value
2. Another one can be manually executed and will in return create a new list item

What I want to happen is for the list items that are created through the Workflow 2 to also execute Workflow 1 when they are created. However, that does not seem to happen, or at least it doesn't happen consistently. In most cases when I look at the Workflow History of the new items that were created through Workflow 2 there is nothing in the history. When I manually create items then Workflow 1 is started without issues.

I can't figure out why this isn't working? Does Sharepoint treat items differently when they are created through a workflow?
