The profile line was built by replacing a leading `$HOME` with `sed`, without a path boundary, and with `$HOME` treated as a regex. With `HOME=/home/me` and `NVM_DIR=/home/me2/nvm`, or with `HOME=/` and `NVM_DIR=/usr/local/nvm`, the profile got `export NVM_DIR="$HOME2/nvm"` or `export NVM_DIR="$HOMEusr/local/nvm"`, which expand to the wrong directory, so nvm does not load in new shells. A `.` in `$HOME` matched any character, a `:` in it broke the `sed` expression, and a trailing slash on it left `$HOME.nvm`. Match `$HOME` literally, as a whole path component, and leave the path absolute when `$HOME` is empty.
