Drools keeps only the last logical insertion in each rules consequence

If a rule contains more than on logical insertion, Drools will only keep the last one, cancelling any previously logically inserted facts. Example:

package com.sample

declare Some
field : int
end

rule "Init"
salience 9999
dialect "mvel"
when
eval( true );
then
with( s0 = new Some() )

insertLogical(s0);
with( s1 = new Some() )

insertLogical(s1);
end

In the above case, drools will only keep s1, but not s0.
