Bug: Creation of new topic based on template overwrites existing topic when topic already exists

Noticed in HowToPreventTemplateToOverwriteExistingTopic:

I've used the form shown in Template Topics in Action to create new topics based on a template. To my surprise I noticed, that existing topics are overwritten without warning, when create is used with an existing topic name. An example can be found at HHsSandbox#Topic_Creation_using_HHsTemplate. Is anybody aware of a workaround?

I've observed later, that an existing topic is overwritten only when create is used shortly after the initial creation. Topics which have been around for some time won't be overwritten. An explanation for this behavior is welcome anyway.
