Let me throw in the consistency argument here:

if you look in staff.te you will notice that:

	optional_policy(`
		oident_manage_user_content(staff_t)
		oident_relabel_user_content(staff_t)
	')

is also in the ifndef distro_redhat block. This is exactly the same issue.
So why would alsa not be in there and oident be in there

Also i could put your questions the other way, i would instead ask why this policy is duplicate.
Its not the conditional block perse that raises questions, its the fact that refpolicy and fedora both use different policy.
Thats in my view the core issue.
