You are making correct assumptions but unidirectional and shotgun do 
not mean the same thing.  Shotgun is a subcategory of unidrectional 
-- they have narrower polar response patterns than other 
unidirectional mics.  Shotgun mics can usually be recognized by their 
extra long shape with many ports along the side (used to cancel out 
sound to narrow the pattern).  Audio-Technica has two stereo shotgun 
mics, the AT815ST and the AT835ST.

Here's a very short explanation of microphone types
