 From a hobbiest's perspective there's likely rarely any reason to be  
able to do the same thing with two different remotes that send  
different signals, but i could see it come up - For example if you  
wanted to have both a feature-rich,  busy/complicated remote but also  
wanted to provide a simpler remote with a relatively small number of  
large buttons on it for basic functions, as for children or people  
with poor eyesight or poor motor control.

 From a business perspective, I've worked for a company that sold  
turn-key video training systems, and depending on the whims of our  
so-called business partners and the desires of customers, there were  
as many as three distinct remotes that might get shipped with the  
training system, and they all sent different signals.

That was a less than ideal situation, and if we had been really on top  
of things we'd have just declined to use any of those remotes and  
bought custom remotes from any of the numerous vendors that sell them  
which would allow us to have one set of IR signals used by remotes  
with different features - but for whatever reason that wasn't how  
management decided to do things.
