As tunenut mentioned it's not a fixed bitrate encoding system.When signals in all channels are not correlated to each other AND have high amplitude high frequency content. Then the resulting bitrate will exceed the maximum set for the DVD Audio spec.
With normal music this will virtually never happen. High level noise and rock music with high compression are likely candidates.
The problem can be 'fixed' by using a slight rollof above 24kHz.
This is the easy way out.It's also possible to lower the bitrate for the rear channels by lowering the bit depth or even the sample rate.
It's also a problem that only will occur for short instances of time if at all.
So measures to prevent encoder 'overload' can be temporary to prevent ill effects.A good mastering engineer should know is business anyway.
It's also important to realize that the original pcm recording and the master are still linear pcm and not affected at all.
