All your expressions herein start with \S and don't take the leading indent into consideration. The next line doesn't start with 'padding', but rather '  padding'.

Even where you are matching, you aren't matching from the beginning of the line, but from the first non blank character.

You need ...\n\s*\1 to skip over the next line's initial whitespace.
