Since the default behavior of alias resolution is to check the stored  
path first, why bother with an explicit path check beforehand? The  
whole point of the alias mechanism is to robustly track files over  
extended periods of time. Resolve the alias, and the system will tell  
you in the process of that resolution whether the file has moved (and  
thus the alias needs to be resaved for optimal efficiency). Bob's  
your metaphorical uncle.
