Barley wine changing color/clarity

I made a batch of barley about 2 years ago. It was really good, just found the recipe when I moved the fridge. I gave out a couple bottles and kept the rest. It aged around 3-4 months before my assistant brewer and I tried it (i actually disguised it as another bottle to make sure he would give an honest effort as this was one of the first few batches i/we (his first) had ever made.he was impresses as well as I was. Luck right?) So here's the weird question. We bottled the whole batch, mostly bombers. On 2 (that I witnessed) while pouring into the glass, and after the pour it went from a cloudy brown, and then you could watch the transformation into a very clear red. It was very cool, and of the bottles that went out someone, only 1 said they noticed the same thing(bomber) has anyone had anything like that? Any reason why that happens? I'd love to repeat it. Thanks for any feedback.
