Summary: Java heap space error

Initial Comment:
I have an xquery code like below, that created java heap space error 

let $x := <persons>
           {
            for $i in (1 to 32000)
            return <person age="{$i}"> seema {$i} </person>
            }
            </persons>         
let $result := for $j in $x//person[matches(@age,3)]
               return $j
return $result

I found that if I were to replace the line  "for $j in $x//person[matches(@age,3)]" with 

"for $j in $x//person
where[matches($j/@age,3)]"

It did not create any java heap space error. I wonder why there should be any error with the first version of code, even though it is pretty much the same
as the second version
