Yes, the straightforward reading of the verse is those he foreknew, he chose. What is not so straightforward is your adding the concept of foreknowledge of what some would do, as opposed to foreknowledge being a choice or calling of someone.
Romans 11: 1-2
I ask, then, has God rejected his people? By no means! For I myself am an Israelite, a descendant of Abraham, a member of the tribe of Benjamin. 2 God has not rejected his people whom he foreknew.
Paul in the same book refers to the Israelites as being foreknown. If his foreknowledge has the sense of choice or calling, the verse makes perfect sense. If it has a meaning of knowing something ahead of time, the second part of the verse becomes meaningless. What did the Israelites do or say that God knew about ahead of time? Well, everything, but that does not seem to be relevant to the discussion.
Peace,

I'm trying to avoid opening the can of worms you have presented with regard to definitions of foreknowledge and preordination so as to keep this simple at the risk of not really addressing the issue but perhaps this will be usefull:
Gnosis often carries the idea of more than just knowledge but also relational knowledge, similar to when we say, "I know you, you wouldn't do that," which is different than just knowing about someone.
I think if you look at the statement "God has not cast off those whom he foreknew," we can get the idea that what Paul is saying is that God knew he would have a covenantal relationship with Israel, and it can be argued that is because he planned it that way, that is, he preordained it, but to then define "pre knowledge" as "pre choice" is going way beyond the meaning of the word itself. If you insert that meaning into "pre knowledge" then you will find "those he pre knew he pre chose" in Rom. 8:29 to be saying, "those he pre chose he pre chose," which doesn't make any sense either.
Neither does making "pre choice" a meaning for "pre knowledge" make any sense in the following:
Acts 26:5 Which knew me from the beginning, if they would testify, that after the most straitest sect of our religion I lived a Pharisee.
2 Pet. 3:17 Ye therefore, beloved, seeing ye know these things before, beware lest ye also, being led away with the error of the wicked, fall from your own stedfastness.
So I think it is safer and more sound to leave prognosis as pre knowledge and not add to it the meaning of pre choice.
You will also find that the early church fathers who had Greek as their language (rather than Latin) agree with what I am saying and did not have the idea of choice with regard to prognosis, which verifies that adding the idea of choice to prognosis was a later invention, possibly as early as the first Latin church fathers.
Following the above line of reasoning will also keep you from the inescapable conclusion to TULIP, that God picked souls to suffer eternally.
