Thanks for answering. I was at my wits’ end trying to think how the behavior of 
those two would differ and even tried a couple of experiments, to no avail 
unfortunately.

I think you're right that `{m}?` is always the same as `{m}`, and I'll
add a clarification to the Guide.

[racket-users] Racket Guide, REs, section 9.5

[Jussi Salmela]

At the end of section 9.5 there is the sentence:

   The non-greedy quantifiers are respectively: *?, +?, ??, {m}?, {m,n}?. 

I don't understand what {m}? is supposed to match because {m} means 'match 
exactly the previous pattern'.
