To make it simpler to explain, lets take a look at the example I have attached. Tasks 4 to 1 have decreasing priority however due to some reason (common in IT projects), developer thought its smarter to work on some part of task 1 first. hence actuals got recorded for task 1 (typically actuals are recorded twice/thrice a week but full review of tasks happens only once a week as there are 100's). Now when its realised that lets get over with Task1 completely - its too late: even if you change priority of task 1 to 1000 it will not delete the split.
