A technique I like to apply when trying to tease out the meaning of the Japanese words and phrases of this project is to input a full sentence or two and then gradually reduce blocks of characters. Sometimes this reduction reveals context and possible meaning within smaller phrases.
By dropping the opening phrase "When you use holy water, " ( 聖水を使うと、) you get ". . . defeat undead monsters such as Scrutons, Zimbi, and Mummies that face you." (. . . 自分に面した、スクルトン、 ジンビ、マミーな。) So "glide away" and "slip away" might be interpreted as forcing a retreat or removing the threat without killing. Why? Because you can't kill something that already died. I think defeat connotes this ambiguity well enough.
If you can buy that, then I'd point out that one meaning of "facing" in terms of defeating is confronting, which doesn't necessarily require adjacency. So I think Kurgan may be onto something regarding holy water as a missile. One way to interpret "Holy water can be used instead of combat/fighting" is to opt out of combat (adjacent atttacking) by instead using either adjacent holy magic or attack with missile fire. Missile weapons can be used in the intermediate JA rules, right? That is a bit apart from combat-understood-as-adjacent in the beginner rules (if I recall correctly), but it shouldn't all rules apply with holy water?
I'm no expert on the nuances of JA interpretation of rules, obviously. (For that matter, I don't always hold my own interpreting the NA rules!) That said, I suspect along with Chwat and his wife that there may be some built-in looseness to this Japanese text. As usual, take your best shot.
