Yes, because the identity transform is processing all of the children of 
all of the elements, the position() when matching on tr is reflecting the 
position in relation to the parent.

Add a template rule one higher in the hierarchy than your test, and then 
only apply the children you want matched.  When they are matched, the 
position() reflects the desired selection.

You don't say what you want done with the tr constructs that don't match 
your expression ... I'm assuming to ignore them.

The more you add to the stylesheet the more you will need to consider if 
priority is required ... it isn't yet, but keep it in mind.

You don't give any test data, but I think what I have below works for 
you.  I only added one template rule.

I hope this helps.
