I had the same kind of problem : Drools stops on the first DSL sentence it can map to.
If you want it to work, you have to be careful about the order you write sentences in your DSL : write them from the most restricitive to the less.

In your case it should be :

This is a "{node1}" in "{tree}"
This is a "{node1}"

Note Drools tools for Eclipse have nothing to change order, so you will have to open your DSL file as a text file to do this ;)

Regards,

Olivier
