That's just habit, mostly.  See "Brace Expansion" in bash(1) for all 
the fun things you can do inside curly braces.  In this case it wasn't 
necessary, but I do it for consistency.  It's useful when you need to 
embed a variable in a string, such as: 

for x in 1 2 3 ; do echo "${x}blah" ; done 

Without the braces you get three blank lines.  With the braces you get 
the expected output.

All generalizations are false, including this one.
