Lots of anon accounts (reasonably) in this thread, so I want to back up as a non-anon former Googler that your experience matches mine. It wasn't "ignore patents", it was "don't look up patents so you aren't influenced by them".
There's no legal reason to worry about being influenced by a patent. The only concern might be boxing your creativity where you can't think of alternative solutions to a problem once you've seen one solution. That doesn't seem like a strong enough reason for a blanket policy.
IANAL but this confuses me.

(Of course: not a lawyer, this is not legal advice)
Your experience matches mine. I think it might even be somewhere in the mandatory periodic training.
Doing a patent search as a software engineer can only hurt you. Better just to route any questions to product counsel.
