Not really. From the perlre:

The following standard quantifiers are recognized:

   *      Match 0 or more times
   +      Match 1 or more times
   ?      Match 1 or 0 times
   {n}    Match exactly n times
   {n,}   Match at least n times
   {n,m}  Match at least n but not more than m times

(If a curly bracket occurs in any other context, it is treated as a regular character.  In particular, the lower bound is not optional.) 

So in the *Incorrect* regex is valid - match any digit followed by, literally, {1,2 (&&JUMP4{1,2SCOOBY would match).
