The way I look at it is that the meetings only happen once and neither Doctor knows it's going to happen until it does. So in The Two Doctors the 2nd, and 6th both experience it at exactly the same time. The 6th doesn't already know it's going to happen as he's lived through it in his 2nd form, as it's not actually happened yet. However once it has happened, the older Doctor would have two lots of memories, what he experienced in his 6th form and also what the 2nd Doctor saw. Time effectivley re-writes itself.”
Yes- I think this is it.
I think you could say that Time Lords have parts of their brains that are in flux due to all the time travel involved ( perhaps why Donna's brain couldn't handle all the 'timey wimey' stuff) When an event involving more than one of him happens, the memory doesn't finally form a proper place in his brain until all of them have experienced the event. Until then that part of his brain is very 'wibbly wobbly', and can't be accessed properly in order to 'remember' the memories that could be stored within that piece of brain which is in flux. I see it as a bit like Schroedinghers cat- it's both there and not there, and not fully formed.
This could also explain somewhat why he acts strangely sometimes and a bit 'wacky'. It must be hard being a time lord, seeing everything that could possibly happen, at the same time as not knowing what will still happen, and having lots of bits in your head that aren't fully there all the time.
Also- in the classic series, the Time Lords were always about to make sure each incarnation got returned to the same point they left, so they could 'cover up' any evidence to ensure no future knowledge was gained or remembered.
I suppose Time Crash could be explained by the Time Lords not being around any more to do the covering up. So whereas in the past the most recent doctor might have been instantly gaining 2 sets of memories at the same time, perhaps with a bit of lag as the memories caught up, or formed in his brain. Time Crash happened to both Doctors on the Tardis, with no Time Lords around for the most recent one. The Tardis could also have facilited the memory catch up and formation.
Just a little theory
