Fun with numbers

From The Guardian: On 27 March, MPs voted against 'Motion B: no deal in the absence of a withdrawal agreement' by 400 to 160.

Also from The Guardian: The Cooper bill [ruling out 'no deal'] has passed its third reading with a majority of only one vote, 313 to 312

So there must be a significant number of MPs who voted against 'No Deal' but also voted against 'No no deal'. The mind boggles. Maybe there are some who just vote against every proposal by force of habit?
