I'm thinking that when Poser normally executes the readscript it sees the figure number :1 and assigns the FBM to Figure 1 (regardless as to the current figure's number). Because if you switch the figure in figure 1 the new fiigure gets the FBM from the readscript so it's not the first figure loaded that receives it, but the figure occupying the :1 slot - ergo it is interpreting the number. But the readscript code is old enough (Poser 3) to not do the correct analysis of the figure # to see if it really does point to the current figure (which I'm guessing was added in Poser 4 along with all the ERC, etc). However perhaps if no figure number is present at all, as in Maveris' BIG discovery, it has to determine an actual figure number in order to be able to proceed and thus gets the right figure number for the current figure. Why would this code be there in readscript when the ERC relate number stuff wasn't? This code to compute a missing figure number would have been needed for legacy purposes back when Poser first started accepting multiple figures - which I suspect preceded Poser 3 and readscript - Poser 2? - to handle figures saved under earlier releases without a figure number. Thus this piece of code would have been included with readscript when it was developed. Just a theory. ;-) Now if I can just get it to work...
