I figured he simply lied about all of his "pasted terminal output".
Notice how the pathname spat out as $0 keeps changing too.

Nonetheless, the result can be reproduced, but only in posix mode.

imadev:~$ bash-4.3 -posix -c $': ${0.8}\necho after'
bash-4.3: ${0.8}: bad substitution
after
imadev:~$ bash-4.4 -posix -c $': ${0.8}\necho after'
bash-4.4: ${0.8}: bad substitution
imadev:~$
