No, it just means that I am not familiar enough with org-element structures.

If preceding object is string than trailing spaces should be taken into 
account instead of :post-blank. If footnote reference or similar object 
has more :post-blank spaces than replace it by string with space 
characters to have footnote's :post-blank in total. Alternatively append 
these spaces to the preceding string.

So stripping the footnote use 2 spaces "  " instead of preceding " " or 
add another " " (unsure if 2 adjacent strings may be a problem for 
export backends).

I was imprecise, but I do not see any contradictions.
