My experience is that it doesn't enforce either of them. I have mine set to auto and have seen it set main level 4 and the output file average 19.7 Mb/s and know it spikes at some points into the 40's. I even tested a 4K clip with auto levels and a low crf to see if it would go past the default level 5 vbv settings and it got up to over 200 Mb/s and averaged around 150's.
