Because it doesn't add any "BuildRequires".

There are two passes. Pass one creates the src.rpm in an environment where
ruby is missing. That alone ("command not found" errors) would not be the
reason for a fatal build error, *if* the results of running ruby were not
used to construct a tag in the spec file. It's really just the empty
"Requires:" line which causes the src.rpm build to fail. Pass two takes
the src.rpm, queries its build requirements (rpm -qpR) and installs
the missing packages into the build chroot. Only then ruby is installed
to be available at build-time.

BuildRequires: ruby
