I would wager that's EP being sarcastic.
Heck if you take last year out when Lebron was incredibly inefficient he has a better career 3PT% in the playoffs than Bird. I get that we all love Bird on here, but his career playoff shooting percentage from 3 is just 32.1%. He has more seasons under 17% than he has over 40% in the playoffs.
To put that into perspective, though, Bird only took ~250 playoff threes... while being a three time three point contest winner. I would not put my money on James in something as comparatively low stakes as a three point contest, so the comparison here seems a little silly (and I'm someone who thinks James comes up positive in most aspects of his career in comparison to LL).
Also, in regards to your "but if you take out last year" comment, I'm reminded of Beavis and Butthead:
"uh… huh huh… well, huh huh… if nothing sucked, and like, everything was cool all the time, then it’s like, how would you know it was cool? huh huh…"
Gotta take the good with the bad.
