That BYO article is from 2011 right? There’s a bit more know about hops now than in 2011.
This has some better more up to date science based info on 4mmp and other thiols and flavor active compounds in hops.

if you were to make a beer with just Citra at 60 minutes I guarantee you there would be no “cattiness” in the beer. Dry hopping (or low whirlpool temps) is the best way to get it into the beer although then it doesn’t survive fermentation nearly as well as other aromatic compounds.
The “harshness” from boiling Citra is more likely due to the higher than normal polyphenol content. Similar results would come from boiling Galaxy.
I’m not saying you should add it at 60 minutes but don’t be afraid of 30 minute additions. There are definitely compounds in hops that benefit from boiling and will make it into even heavily dry hopped beers.
I’ve been messing with adding decent amounts of Simcoe and Cascade at 30 lately (no beginning of boil addition) and the difference in the final beer was pretty eye opening. You could definitely pick out aroma contributions of the beer with the 30 minute addition even with a rather large DH charge. I went into these experiments doubting that I would see a big difference and was pleasantly surprised.
To me beers that are only whirlpooled and dry hopped lack depth and character. You can create much more interesting aroma and flavor profiles by adding certain hops at certain times on the hotside.
