The definition given is that of an equihopper, not an equileaper.
Equileaper
Combination of all possible (m,n) leapers where m and n are both even. This piece can leap to any square that is a multiple of 2 squares distant both vertically and horizontally.

Joost has given the right definition of Equileaper. Another way to describe it is Equileaper can visit/attack every square an Equi-hopper can. No hurdles needed !
