I don't think the last part is correct.I believe it is intended to disrupt the normal flow of chakra, rendering chakra control useless.
WIki entry on chakra control
Because chakra takes time and a great deal of training to gradually build up, the key to its use is not actually having large amounts of chakra but instead being able to sufficiently control and conserve it. This is called chakra control (チャクラコントロール , chakura kontorōru). In order to have good chakra control, a ninja should only mould as much chakra as they need to perform a given ability. If they mould more chakra than is needed, the excess chakra is wasted and they will tire out faster from its loss. If they don't mould enough chakra, a technique will not be performed effectively, if at all, likely creating problems in a combat situation.
disruption in chakra flow=overall harm

If you go on ahead and read the next pages after the link above, kakashi states Kyuubi was messing with Naruto's control but as we know that brought him no harm whatsoever.
But as Ebisu says, 0 chakra equals death which means inserting GF into the chakra surrounding an organ and destroying the chakra there = death for organ. Which could yet again imply GF is like poison chakra...but again all this is pure speculation on my part.
