From the documents I know

unigram: |output tag| x |all possible strings expanded with a macro| bigram: |output tag| x |output tag| x |all possible strings expanded with a macro|

Now I have configured a template like this

Unigram
U01:%x[-1,0]/%x[0,0]

in this case is it bigram or unigram ? And how many features it will generate, L N or L L * N?
