I've always been under the impression that both the terminal and attributive endings reduced to -i, and then merged. Could well be wrong though.

Can you elaborate?
Well, the glottal fricative is a phoneme like any other. Just because it has a certain tendency to disappear in certain languages, doesn't mean that this same change will happen in others. In fact, in many languages /h/ is a very stable sound. In others, it might be an emerging sound. And in others again, it might be a transitional change, and the end result could well entail its entire disappearance, lead to a different phoneme such as a glottal stop, or leave behind a trace such as aspiration or breathy vowels.
From a phonological point of view, the change /h/ → /∅/ can be discouraged if the resulting sequence violates phonotactic rules. For instance, its entire disappearance could lead to undesirable consonant clusters and vowel sequences, and it may also result in the resyllabification of entire syllables. Another issue is that the existence of /h/ might be tied down to a process of debuccalization, which means that it could very well correlate with a voiced counterpart /ɦ/. Should one disappear, there's a very strong chance the other disappears along with it. And their disappearance could bring about innumerable homophones. A third issue is that /h/ may not be what it seems and could, in fact, encompass multiple realizations, as is the case of Japanese: [h ç (ɕ) ɸ]. The question here is, does the entire phoneme disappear, or does only a certain realization of it disappear?
Now, it's not to say that it absolutely can't happen, but in a language where all of these issues are relevant, it's far less likely that the change /h/ → /∅/ will fully take place. Instead, you're more likely to see other phonemes or phonetic qualities take its place in order to fill the void; and in many other cases, the change will be incomplete and will only take place under restrictive circumstances. Perhaps here a better question to ask would be, under what conditions do all of the languages above exhibit
h → ∅.
