Correct. On the image below you can see the front fans. note how you see the part where the motor is. I drew lines to indicate airflow path:

here is the site: http://www.coolermaster.com/case/mid-tower/masterbox-5-black/ if you scroll down you can see various configs they have with it. Note that on all of them the front fans are intake.

for front mounted radiators, intake is the better choice.

It means you're bringing cool air in over the rad. Yes the air will warm up a little coming through the rad, but it's not going to make things warm up too much, as long as you keep the airflow optimal with exhaust fans in the back/top.

In through the front/bottom, out through the back/top.

The other choice is to top mount the rad as an exhaust.

it depends which way you face the fans

some fans have an arrow on the side which shows which way the air flows.

it's not the side of the rad the fans are mounted on that makes them intake or exhaust, it's which way round the fans are mounted

example, if you have a fan facing so it's bringing air in, regardless if it's on the front or the back of the rad, it's still an intake

If it's on the front, it's a push setup. If it's on the back, it's a pull setup.

Push - pushing air through the rad
Pull - pulling air through the rad
Push/Pull - fans on both sides of the rad
 
no you were correct the first time, it is indeed backward. it is sucking air from the inside and he has the rear fan sucking out as well. You can tell by which side the motor mount is on and by the shape of the blades in this case. Note how they are angled to be scooping air from that side. Almost all fans pull from the open side and exhaust on the side with the mount. There is a reason that vid has so many dislikes:

here are some pics of mine (dont mind the dust, it is very dusty here). In my case I was able to mount the fans as intake on the front in their normal spot then attach the rad to the back of it so it is forcing air through the rad from the front. My rear fan is an exhaust as normal. You can indeed mount the fans to the rear if you like, just make sure you have proper airflow in the case.

mine has only 1 fan as exaust(rear) and 2 fans as intake on the front, so if i put the rad like you i guess it wont be a problem, my case is the coolermaster masterbox 5
