I want to ask about the logical indexing at the end. This is from Mathworks website. Looking at B(TF), it doesn't seem to convey anything meaningful. What am I missing?

You're using an older release of MATLAB. Using a cell array of char vectors rather than a string array:
rng default % So we generate the same A each time
A = randi(3, [3 3])
B = categorical(A, 1:3, {'red'; 'green'; 'blue'})
TF = B ~= 'red'
nonred = B(TF)
