It does not really have to do with "conditionals" per se. You can
observe similar behavior with standalone lists.

% bash --version | head -n 1
GNU bash, version 5.0.17(1)-release (x86_64-apple-darwin18.7.0)
% cat /tmp/pe-test
: "${x!y}"
echo foo

    : "${x!y}"
    echo no bar
echo bar

: "${x!y}"; echo no baz
echo baz
% bash /tmp/pe-test
/tmp/pe-test: line 1: ${x!y}: bad substitution
/tmp/pe-test: line 5: ${x!y}: bad substitution
/tmp/pe-test: line 8: ${x!y}: bad substitution
