I don’t think I have enough info to generate good hypotheses yet, but it seems odd that the original would be intellectually more degraded than, e.g. Quirrelmort (unless the Quirrel himself has/had a formidable brain already). The “pretending to be brutish and lose” plan is also improbable because it violates Malfoy’s Rule of Three. (OTOH Lucius, while clever, is not the smartest plotter around, and knows this, so perhaps the rule doesn’t apply to truly superior plotters.)
The original might not necessarily be ‘degraded’ compared to Quirrel—he had different strategies, yes, but Quirrel has observed a lot of things since ‘his’ defeat. Those could explain his change in strategy.
