_2 tells to take the last item and us it to cut and leave it out of the results
from the Dictionary
file:///C:/Program%20Files/j602/help/dictionary/d331.htm
"The fret 0{y (the leading item of y) marks the start of an interval
of items of y ; the phrase u;.1 y applies u to each such interval. The
phrase u;._1 y differs only in that frets are excluded from the
result. In u;.2 and u;._2 the fret is the last item, and marks the
ends of intervals."
