They best stop before having sex. Everyone knows, if you have sex in a zombie-infested setting, you are very next to die.
Hmmm, AFAIK the classic formula is that a woman who has sex in a horror movie dies first. However, if two women do it with each other, the system kind of breaks down, as it is no longer clear who of them should die first. Following this train of thought, it may be possible for them to deadlock the system and turn on the god mode for the rest of the story.
Your method might be subverted by killing both simultaneously(perhaps while they're getting redressed). Now, if the killer won't interrupt a couple in the act...
This subversion is a trick of perception, however, as general relativity teaches us that true simultaneity does not exist in nature, ergo one of them would die first in at least one reference frame. However, since which one specifically is not defined (see above), it would create a space-time paradox, which will resolve itself into both of them surviving in all reference frames.
Thus, under the premises of general relativity, we conclude that yuri >> zombie apocalypse, q.e.d.
