"Copies the elements of vector from between start and end
to vector to, starting at at."
So start and end identifiers the elements of from, and at
identifies the index in to where they get copied to.
Perhaps a re-phrasing might help:
The elements of vector 'from' between 'start' and 'end'
(as defined in section 1.3.3) are copied into vector 'to',
starting at index 'at' (replacing elements from 'at'
