Unfortunately, game summary portion of the rulebook contradicts main rules in few cases. Use the real rules instead.
And technically the chart doesn't say that when Walker moves, it moves at Combat speed. Instead it states that if Walker moved Combat speed (which it doesn't), it could shoot all of its weapons at full ballistic skill.
On the same page, there's also the error in "Expliodes" result in which it is stated that models disembark but are limited to 3" move, which is obviously copy-paste error when you read the actual rules.
