Initially, the star would have been very metal*-poor (only a little lithium left over from the big bang.)
Given that star went supernova only 630My post-big bang, it is reasonable to assume it had a minimum mass of 3-4 Msun, and a maximum of probably 10-15 Msun. Those numbers suggest that it did fuse right to nickel.
The interesting thing (what the parent was probably refering to) is not really the final metallicity (which is merely a function of the star's mass) but the initial metalliticy, which cannot.
*To an astronomer, anything heavier than helium is a metal
