Try instead:
tr.setmode('br1.b1','close')
tr.setmode('br1.b2','close')
tr.setmode('br1','close')
tr.close('br1.b2')
tr.close('br1.b1')

My solution above make any sense till I read the docs,
http://epydoc.sourceforge.net/stdlib/public/Tix.Tree-class.html
say:
setmode(self, entrypath, mode='none')
[snip]
... If mode is set to close, a (-)
indicator is drawn next the the entry.
... The
open mode indicates the entry has hidden children and this entry can be
opened by the user. The close mode indicates that all the children of the
entry are now visible and the entry can be closed by the user.
