Do the current month nifty future data/chart provide historical data for expired future contracts as well

[coolankurmahe]

I can see the data for NIFTY30MAY24FUT symboltoken = 46930 (which is future contract for current month).
But it also shows in charts and data pulled by getCandleData API the data for previous months, past years though the future contract lasts for only 3 months.

Does this mean current month future contract data shows historical data of expired future contracts for each month ?
example: currently NIFTY30MAY24FUT (future contract for May expiry Nifty) shows data for :
May - current month expiry
April- April month expired future data
March - March month expired future data
etc etc ?
Is the above assessment correct ?
If yes, does this also hold for stock futures ?
