I was just proposing it because it:

(a) Eliminates use of a temp var if you want to avoid erroneous multiple 
dereferences (no autocomplete in Templates!), reducing context namespace 
pollution
(b) is a little nicer in that you don't need to refer to the full name of 
the property within the block.

That's all - make templates easier to read and write.
