Yes, as the code is run again to re-build the vignettes.

The main use of BuildVignettes: FALSE is when building the vignettes 
requires unusual facilities -- presumably not R ones as it does not turn 
off running the code.  However, for a FOSS package, the means to 
re-build the vignettes has to available to others, and CRAN therefore 
tries it so see if all the sources are available.  Almost every time we 
uncover some problem with the sources and stale vignette PDFs.
