Fortunately today after doing some tests I have found why it does not work and how to fix it. When pipeline goes to PLAYING state, it updates its base time to current time. To fix this, you have to get base time from one pipeline and set it as base time for second one. I do this just after setting state of 2nd one to PLAYING. You also should remove lines which change start time, this produces some strange results.
