Question: what’s meant by “pre-correction of bad meme” here?

(⍳⍤≢=⍳⍨)⍤(∪⍳1/⊢) ⍝ Pre-correction of bad meme (⍳≢⍵)=⍵⍳⍵

Also, a related question about the 1/⊢‬ part: why make a scalar probe into a vector before searching in the Unique/Nub? I see that doing the search without increasing the probe to rank 1, as in (∪⍳⊢)'A'‬, does not give an error…
