Obviously it doesn't replace Paula or anything like that (that's impossible without a huge amount of work, as non-AHI programs tend to just hit the hardware).
You should be able to hijack audio.device too.
As they ask about software that runs full speed without sound enabled, but doesn't when sound is enabled. The only thing that could be saved would be AHI software mixing and potentially 14 bit processing when using Paula.
So I believe the question the wanted answering was likely to be: Is this going to be as slow as using AHI with paula?
