residual with protest in vegan

I am using protest (in vegan) to assess the concordance between NMDS 
scores, as shown below:

fishbug.fit <- protest(scores.bug, scores.fish,permutations = 9999)

I would like to get the average residuals from protest.  When I use 
residuals(),

resids.fit<-residuals(fishbug.fit)

which residuals is this returning to me?  Are these the average 
residuals from the 9999 permutations or are these the residuals from the 
most recent permutation?

Thanks for any help,
