Yeah, you're right! Actually I knew this difference alrady and because of the 
asynchronous call I want to use the start() method, but it isn't working with 
the php executable, whereas the execute() method does. My guess is a different 
system environment or a problem with STDOUT, STDIN or STDERR.

But I want to proof it, that's why I asked for the differences.
