The comment is true only if the preceding code has arranged it so that
is so...

Well, I'd suggest just try it and see...

Lmax is only the max if there are a total of four elements in B --
you've concatenated four sets of three first so clearly that isn't going
to be so. The minimum will, of course, still be the first.

If want/need them sorted for some other reason, then the maximum one
will be B(end) (NB that the "1" first subscript for a 1D array/vector is
superfluous and can be omitted.)
