No, the arrays are 2 differently led matrices. The first is the regular led, 16 long and snaked back on itself, and the second is led strips 16 long, but kept in number order from left to right.
And yeah, the result is a single white pixel, moving left to right but pending on which setup you use.
parts of this code are probably usable :
