This is most likely due to the sheer length of these trains--it isn't even unusual for premium services to have well in excess of 15 coaches. Trains with non-air-conditioned classes (basically anything with bars on the windows instead of glass) can easily hit 18-20 cars and up. There is a limit to how many cars can be powered off a single generator car (or HEP-equipped locomotive), usually about 15 or so cars max.
