Hey bud, if it is created before the timer appears in the guide it obviously is a Dish Pass. Of course, that searches on strings within the Title or in the body of the guide entry.
When you create a recurring timer it does not search for strings or exact matches, but rather when you create the timer it looks for a coded identifier for the show and uses that to identify all episodes. My recurring "New" Timer for the show in question functioned as it is supposed to and the re-named show is going to be recorded even tho the name no longer matches the name in my list of timers.
Instead of saying something you clearly do not understand is "hypothetical" you should maybe do some homework before posting so as to not lull some people into thinking you know what you are talking about.
IAWTC- And I thank the OP for pointing out the potential conflict. Some folks will benefit from checking their timers.
