In simple Bare Act / Code legal drafted English let me try to place the actual respective Bare Act / Code before you first (read the bold highlighted parts);
S. 498a IPC reads as follows:
498A. Husband or relative of husband of a woman subjecting her to cruelty.

Explanation-For the purpose of this section, "cruelty" means-

(b) Harassment of the woman where such harassment is with a view to coercing her or any person related to her to meet any unlawful demand for any property or valuable security or is on account of failure by her or any person related to her meet such demand.
Now take a look at Definition of Domestic Violence (S. 3 of the Act)
3. Definition of domestic violence.-

Explanation II.- For the purpose of determining whether any act, omission, commission or conduct of the respondent constitutes "domestic violence" under this section, the overall facts and circumstances of the case shall be taken into consideration.
Now are there any further comments left to elucidate here if allegations should be ditto and or should vary then where comes the question that does S. 300 (1) of Cr.P.C. is wider than Art. 20 (2) of the Constitution?
While, Art. 20 (2) of the Constitution only states that 'no one can be prosecuted and punished for the same offence more than once', S. 300 (1) of Cr.P.C. on the other hand states that “no one can be tried and convicted for the same offence or even for a different offence but on the same facts and or on different facts”. In the present query although the offences are different but also the facts are also different and no verdict of respective Courts has been announced yet. Hence, S. 300 (1) of Cr.P.C. applies or not is too early a question is my opinion.
I offer myself for discussion on my above reply only by ld. brothers.
