Do you have an example of error messages which are returned with such 
'mixed' paths in them?

Unfortunately, this is a general issue. Quite often the values you might 
need to use internally to actually run code will be different from those 
which users might expect. So some 'formatting for display' is always 
generally required in user-facing messages.

A similar situation to this is that of locale-specific number formatting 
(which, admittedly, LiveCode doesn't currently support).

In the UK, we use '.' as the decimal separator; in many European 
countries it is ','. It is easy to see why you need a fixed way to 
represent numbers when running them through script - i.e. using '.':
   put item 2 of "1.05,2.05,3.05"

If you used the user-formatted version of numbers you might end up with 
trying to do this:
   put item 2 of "1,05,2,05,3,05"

Which would, obviously, give you a completely different result! 
Filepaths are no different to this, and the same runs for dates, 
currencies, ...
