I don't think that the coaster section is long enough to justify a MCBR. As you can tell, as soon as the boat has cleared the splash area, the next one is ready to crest the lift hill. Unless they had a double station like Poseidon there's no point in having a block brake section, mainly because the dispatch rate is never going to be short enough for a boat to be stuck on the lift hill waiting for the previous one to clear the block ahead.
Plus I seem to recall that the owner of Nigloland specifically asked to avoid those block sections so as not to break the flow of the ride (and probably make the ride easier to maintain and operate).
