That's for UDFs. For methods in CFCs, you var-declare local variables so they don't clobber any variables with the same names in the VARIABLES scope of the component itself.

RE: var keyword in cfcs ... needed for query names?
I use cfset var local = StructNew() at the top of my functions, and then in the body of the function you could say cfquery name=local.queryName without worrying about it. You are basically creating a local scope for use within the function, and I find this much easier to stick with then varing each variable at the top of the function.
