[FMA:Brotherhood] Does Al know more about human transmutation because he sacrificed more of his body compared to Ed?

In Ed's case, he went through the Gate and was shown everything but was cut off. Then he mentions he's almost there to knowing the secret to human transmutation but his sacrifice (his leg) was not enough of an exchange.

I assume Alphonse also went through the same thing and since he sacrificed his body, does he know everything? If he didn't go through the same ordeal, then what did he and the Truth talk about? How can he transmute without circles?

I believe when Ed is talking with Izumi they agree Al must have seen more of the Truth than either of them because he lost his entire body. However, the ordeal was intense enough that Al cannot remember it.  He does eventually remember some (since he no longer needs to draw Transmutation circles), but it's unclear just how much he remembers and whether or not it is more than Ed and Izumi.
