Your initial assumption is correct. If one visit of a region uses X cells, all subsequent visits must also use X cells.
‘Enter and Leave’ mean exactly what you’d expect them to: crossing the boundaries of the region. Hence, the loop must indeed cross the boundary of each region at least 4 times.

I'm a little bit confused here. If a region is visited only twice, are the number of visited cells per visit still the same? Similarly, if during one visit of a region the loop uses X cells, does this mean any future visits of that same region must use exactly X cells and no more or fewer?
EDIT: Also, what does "enter and leave" mean here? Does the sentence "enter and leave each region at least twice" mean that the loop must cross over the boundary of each region at least four times?
