Hello all. Are there any known limitations for using a derefernced reference to a shared variable?

I.E. is this code: 
my $var1 : shared; 
sub vary {
 $var_ref = shift ;
 lock ($$var_ref);
 $$vary_ref = 1 ;
}
vary (\$var1);

equivalent to this code? 
my $var1 : shared; 
$var_ref = shift ;
{ 
lock ($$var_ref);
 $$vary_ref = 1 ;
}

Thanks.
