In the second \Z line, you're missing a tick mark.

    \Z'\v'1m'\\$2\v'-1m''
            ^
That takes care of the disappearing S, but still deposits a
small space before the beginning of the word, Second.

The only way I know of to get rid of the space is:

    .de amac
    \Z'\v'-1m'\\$1\v'1m''\Z'\v'1m'\\$2\v'-1m''
    ..
