For the same reason he referenced the ABS: he doesn't know any better.

An alternative reference would be https://mywiki.wooledge.org/BashFAQ/006

But I did not cite that in my first response, because the first paragraph
of the actual question led to an entirely different problem which makes
the "indirect reference" syntax and all the stupid shell hacks to reverse
it completely moot.

Plus, if the goal is to index information by string keys, you should be
using an associative array instead.
