Yes. That's one of my concerns - all of the max/mxl tubed merckx' frames I've seen have the tubes as per your link. However, the earlier post showing 1992 max tubed corsa extra seems to be the other ( normal? ) way round.
Here's Anvil Bikeworks' article on Max:http://www.anvilbikes.com/?news_ID=18&catID=3
The real MAX, which is probably most famous as the tubes used to construct the Merckx MX Leader (except the MXL’s top tube and seat stays which weren't the original MAX shape)...
The real MAX top tube is based on a 31.7mm tube and biaxially ovalized to 37.5x26mm with a .7/.4/.7mm butting profile. When installed on a frame, the 37.5mm axis followed the long axis of the head tube yet traverses the seat tube, meaning it is significantly wider than the seat tube, which creates either a really weird looking lug or a whole bunch of cool opportunities depending on your point of view.
So a Corsa Extra built with MAX uses the standard Max top tube, but the MX Leader has a different top tube (and seat lug) with a different orientation of the oval.

Que les branches hautes font,
Pénétrons bien notre amour
