This is feature. 

All output_test_stream validation methods by default flush the 
stream afterward so that you can keep print/compare loop without 
caring about clearing the stream content. If you want to perform 
several checks with the same buffer, specify parameter 
flush_stream=false. This parameter is supported on all comparison 
methods.

I'll update documentation to make it clear.
