What it is
Google Updater keeps the last update package it downloaded for Chrome and each other Google app here, at most one per app, so it can apply smaller differential updates next time. The copy in your Library folder belongs to the updater for your account, and the one in the main Library folder to the updater for all users.
If it's removed
The next update of each Google app may download the full package instead of a smaller update.
How it's removed
