I think the reason is pretty obvious if Legacy liked a post stating to temper expectations of UCM. An knowing what he did reveal about one of the scenes, I can understand why. (As a preface, it's certainly a "your mileage may vary" kind of thing on what was revealed. Myself I have no issue with it, though others might see it differently.)
An to be honest, if you keep your expectations in check on everything, then it's easier for everything to pleasantly surprise you. However if you're going in with the firm mindset that a particular house is gonna' be a GOAT, then it's going to be easier to end up disappointing because it just can't reach one's personal expectations. (Even if it ends up being a great house!)
