Stacking in Relative Clauses

[Andromeda]

Dear Teachers,

1. The one person that I met that really impressed me was John.
2. John, who I met in Cambridge, who really impressed me, always replies to emails.

The author of a grammar book whom I am now reading says that defining clauses like the type in Sentence 1 allows for "stacking". As to sentence 2, such stacking in non-defining clauses is not permissible. He did not elaborate on his reasons.

Could someone tell me why sentence 2 is wrong?

So sorry about that.

I have edited it as I could not delete the post.

Thank you.

I have edited it further so that it's in the standard font and font size. Please try to follow that format in future posts.

Sentence 2 would be correct with "and" before "who really impressed me". Without it, it looks like "who" refers to "Cambridge".

You don't need to know why it's wrong—just that you can't stack non-defining clauses in such a way.

You could fix sentence 2 by conjunction, like this:

John, whom I met in Cambridge and who really impressed me, always replies to emails.
