Manual page of dpkg-maintscript-helper suggests so:

	Many of those tasks require coordinated actions from several maintainer
	scripts (preinst, postinst, prerm, postrm). To avoid mistakes the  same
	call  simply  needs  to  be  put  in  all  scripts and the program will
	automatically adapt its behaviour based  on  the  environment  variable
	DPKG_MAINTSCRIPT_NAME  and on the maintainer scripts arguments that you
	have to forward after a double hyphen.
