Yes it does; if you will not add ${python:Breaks} in debian/control,
that's what dh_python2 will generate actually.
Packages with public modules do not really care about default Python
version usually so why should they depend on python package¹?

Breaks will warn user if an upgrade of python can break some scripts with
/usr/bin/python in shebang, but python-foo packages can still be usable so
I prefer Breaks (because it's easier to override). If APT doesn't deal
well with Breaks, please report bugs against APT (with patches if
possible :)
[¹] if package ships .py files, there's a dependency on python package
due to pycompile/pyclean scripts, but if package is providing .so files
only, there's no need for "python" in Depends
