I think this is expected behaviour. The first line has been parsed,
using the default FS value. *After* parsing it, you're going to set
FS to a new value, so it will affect the next (and all following)
lines.
The correct ways to do it:
. use the -F . option, or
. use ``awk 'BEGIN {FS="."} {print "cp " $1 ...}' ''
