Turns out this is true. I googled it and you are right.
I definitely read Civil War though and the only books I was buying from Marvel at that time were Bendis written books (or so my memory assumed). So perhaps he wrote some things that were tie-ins, or the Iron Man announcing to the world who he was in a Bendis book? Like whatever name the Avengers book was (the new, the secret?).
Bendis took over Iron Man in 2015
Bendis wrote The New Avengers, which might be what you’re thinking of. Apparently he wrote the first two volumes, which lasted seven years. I didn’t realize he was on it so long. 
Brubaker wrote Secret Avengers. Also from that era. He’s another favorite writer of mine…
I forgot about Brubaker. I loved his Captain America, I haven’t been able to get into the series as much after he left it.
That’s pretty much how I felt when I discovered Bendis, he was writing Daredevil, not a character I really care for, but I loved the story. Bendis left and Brubaker took over, it was still great! Then when Brubaker left… so did I.
Bendis is like a comics Tarantino…
Good at his specialized genre, but not a good fit for everything.
It’s not that I don’t like him evolving, It’s just rapid change over 2 years is very poor and feels shaky. If we were to get a few more years of Tomasi, Gleason, Jurgens, and whoever came next, then I would be ok with John growing up because It would have felt the idea has run its course and now John can move on.
This is exactly what DC should do, work him up to a more heavy title over time and keep his focus on one book
That’s a perfect character for him.
The thing I said about Bendis, I’ll take some back. He is a talented writer. What change my mind? I found out today that he actually co-wrote Marvel’s Ultimate Spider-man, which was one of my favorite series.
