2233
 - it should not match because it does not meet condition of Regex 1 and is meeting condition of Regex 2

33QQ2
 - it should match because QQ matches Regex 1 and 33 matches Regex 2

AQQ44
 - it should match because QQ Regex 1 and 44 matches Regex 2

AAKQQ
 - it should match because AA Regex 1 and QQ matches Regex 2

QQ234
 - it should not match. Even when it matches Regex 1 and Regex 2 condition with same QQ, I want second condition to validate other part of string than first so after it matches Regex 1 - it does not find part that match Regex 2.
