NFHS Test Question driving me nuts (as usual)

So, if it is "True", then players not occupying a marked lane space must remain beyond the vertical plane...
However, the rule states “may NOT have either foot BEYOND the vertical plane of the free-throw line extended”

Which side of free-throw line extended is "beyond" in the question and which side is "beyond" in the rule?

BTW, NOT using all caps to imply yelling, but simply to highlight the words in question.
Thanks
