For a good technical reason: the version installed on the computer may not really match whatever the version on Google Fonts serves (fonts have notoriously no semantic versioning aside from some programmer-oriented fonts, examples of these outside are Segoe UI (changed between Windows 7 and 8) and Liberation fonts (some versions notoriously lack some glyph symbols) and on Google Fonts platform the Exo and Exo 2 problem (which was resolved by renaming the second version to Exo 2)).
