I think those probably got cargo-culted in there at some point.
They're visibly dead code, because there are no pg_amop entries
for BRIN opclasses with amopstrategy 13 or 14.
This comment that you removed in 2f70fdb06 is suspicious:
# we could, but choose not to, supply entries for strategies 13 and 14
I'm guessing that somebody was vacillating about whether it'd be
a feature to support these old operator names in BRIN, and
eventually didn't, but forgot to remove the code support.
