Well... not quite.
In 'cut head and tail' mode of the auto-split function silence must be at least -60 dB, and so it will cut off reverb tails. If you try entering a threshold of say -90 dB, it automatically jumps back to -60 dB.
In 'split between silences' mode, I can enter -90 dB, but it cuts off at about -80 dB nonetheless.
