Doubt on GTK strings

[Rafael Ferreira <rafael f f1 gmail com>]

The message catalog (PO) of GTK+ "po-properties", which can be found
in [1] contain strings like "Snap edge set", "Cell background set",
"Editability set".

I understand "set" is used as similiar "define". However I'd like to
confirm if it is something like e.g. "Snap edge definided", which
means Snap edge was enabled.

Does someone know if my logic is correct?
