Does ritual "strength" in this age mean the strength of its effects or only the time remaining until it hits 70% and expires?

In a previous post, before "ritual destroy" was implemented, it sounds like the latter:

But now that there is "ritual destroy," does it still mean the same thing? I.e., it has nothing to do with the strength of the ritual's effects?

Thanks.
