Because many water-based personal lubricants are hyperosmolar, such formulations, applied rectally, may induce similar damage."

I would not use a lubricant with a Spermicide for anal--ouch! I can see where any lube, water based or not, with a spermicide would be damaging; silicone would be uncomfortable as well since the activity even with a water based causes skin cell damage. If you read the "Methods" of the study and the outcomes much is explained.
Blink...I would think your only answer, or true/valid question, is to use the spermicide
in the vagina and a
PLAIN water based lube with no spermicide for anal!!! For geez sake why would you put that nox 9 or any spermicide in the anus? This has to do with the small micro-tears which occur on women [or men receiving anal] due to the stretching and the lack of normal use [intended for a one way EXIT] being painful...
OUCH !
The micro-tears associated with anal intercourse
regardless of; N-9, detergents, poly or latex condoms, etc. will result in tissue damage since the anal cavity is not naturally intended to withstand such tissue damage. Add any compound and the result of damage and pain manifests. The vaginal canal is a different tissue structure [tougher] v. colon wall [rectum/sphincter muscle] structures by the mere layering of tissue.
