the point is parens (the correct term. brackets are []) is they will
grab the match inside them and store it in $1 and friends. grouping
without grabbing is more efficient and also tells the reader (that
person again! :) that they shouldn't look for using $1 (or whatver
number) after this regex is used.

nope. you mean (:?imgres|images|products).
uri
The correct syntax is (?:imgres|images|products).
The wrong syntax appeared in 2 messages and it might cause confusion.
