What happens when I reuse a study object with a global condition?

Global conditions appear to be attached to study objects but are actually part of a workflow. They are copied with study objects in the following way:

If a study event contains a form with a global condition, the global condition is actually part of the study event. When you use the Libraries tab to copy the study event from a study to a library, the global condition is copied. The global condition is not copied if you copy only the form.
If you use the Libraries tab to copy the study event from a study to a library, publish only the form, and copy only the form into a study, the global condition is not copied into the study because the global condition is part of the workflow at the study event level.
When a global condition is on a study element or study event that is created directly under the study design in the Project Explorer, the global condition cannot be copied from a study to a library. The global condition is actually on the study design, and you cannot copy a study design from a study to a library.
