It’s legal, because a foreach loop iterates over a list, not an array. In this case, the list consists of the elements in the array @files, followed by the elements in the array @files2, followed by the elements in the array @files3. The lengths of the arrays are irrelevant.

See perlsyn#Foreach-Loops and perldata#List-value-constructors.

Hope that helps,
