Actually, it does.
coldfusion still checks the query scope first.
<cftry>
<cfset foo = queryNew("id,url","integer,varchar")>
<cfset QueryAddRow(foo)>
<cfset querySetCell(foo,"id",1)>
<cfset querySetCell(foo,"url","http://www.houseoffusion.com";)>
<cfloop query="foo">
<cfif structKeyExists(url,"bar")>url.bar exists!</cfif>
<cfdump var="#url.bar#">
</cfloop>
<cfcatch type="any"><cfdump var="#cfcatch#"></cfcatch>
</cftry>
This generates the dereferencing error on the structKeyExists line ...
because it's looking at url in the query, not the url scope.
