I doubt I can explain this accurately, but I took the original
phrase as that if and only if all pages of the table are marked
as "requires freezing" by accident, all pages are frozen. It's
quite obvious but it is what I think "happen to require freezing"
means. Does this make sense?
The phrase might not be necessary if this is correct.
