When it sees one argument, git-config treats that argument as a key to be retrieved. When given two, the second is a value to be set. E.g.:
$ git config foo.bar
$ git config foo.bar some-value
$ git config foo.bar
some-value
So your command was interpreted as a request to fetch the value, which doesn't exist.

Hopefully that explains the response you saw; we do not emit an error message when a key isn't found, which makes it easy for scripts to do things like:
value=$(git config foo.bar || echo default-value)
without being unnecessarily noisy.
Usually we'd catch an error like yours and complain, because the key is syntactically invalid ("=" is not generally allowed in key names):
$ git config foo.bar=some-value
error: invalid key: foo.bar=some-value
But your argument actually _is_ a syntactically valid key, because of the dots. In a three-level key like "one.two.three", the second level subsection is allowed to contain any character (including "=" and more dots). So your "user.email=alt.email@alt.domain" tries to look up the config represented by:
[user "email=alt.email@alt"]
domain
Which of course did not exist.

Yes, everything is working as intended. The documentation in git-config(1) seems to be quite poor at describing the various operating modes, though.
