I don't know but it works on mine. What's the problem you are facing? 
The new FS will only apply to the following lines, not the current one. 
(And you'll also need a rule for lines without /#separator/):

$ echo  -e "#separator ;\n1;2;3;4\n" |\
    awk '/#separator/ {FS=$2; print "sep",$2} !/#separator/ { print 
"field3",$3} '
sep ;
field3 3
