IMO the wheeling of less than 90 degrees is only applicable for the normal movement. The extra movement of up to 80 paces is exactly that. If you did a wheel of 80 degrees and then moved straight forward to make contact, and then moved up to an extra 80 paces then I don't see any issues with the way in which the extra 80 paces is moved for two reasons : there is no exception in the EMTLUICC section, and it specifically says 'this is extra to normal movement'.
Just my opinion....
