Are these LDS scriptures consistent with LDS doctrine?

In an answer to this [question](https://christianity.stackexchange.com/questions/23931/why-is-god-the-father-referred-to-as-eternal-father-in-lds-writings-when-he-is) Calvin quoted some LDS scripture from this [search](http://www.lds.org/scriptures/triple-index/god-eternal-nature-of?lang=eng) on the LDS scripture site. It seems that the word "eternal" might mean continuing forever from some point in time in LDS theology, rather than the forever past until forever future as it does for many Christians. However, some of these specifically say from forever past to forever future. How can these scriptures be consistent with their "eternal progression" doctrine? >God is same yesterday, today, forever: Morm. 9:9 No change here, so no eternal progression? When this sentence occurs in the Bible, it is usually believed to refer to forever past as well as forever future, however it could be from "sometime past" to "now" to "forever future". >God knows all things, being from everlasting to everlasting: Moro. 7:22 This definitely refers to eternity past to eternity future. >God’s course is one eternal round: D&C 3:2 OK, this could be future only, unless round means it's an unbroken cycle. >God is endless: D&C 19:4, 10 No end in either past or future? Or could it be no end in space? >God is infinite, eternal, unchangeable, from everlasting to everlasting: D&C 20:17 Past eternity to future eternity, no eternal progression? >Endless and Eternal is God’s name: Moses 7:35 OK, maybe a beginning is not considered an end, so one-direction eternity might work. Am I seriously misinterpreting these statements here?
