"...is it normal that the reconsideration visa will get cancelled within 2 days from submission date..."
In the Schengen regime, they don't have a 'reconsideration visa'. So your application would have been treated as a fresh application
within your history of applications.
If your previous application was unsuccessful, they would focus on the corrective measures you have taken to see if you now qualify. Based upon what you wrote, you made it real easy for them and they were able to give a proportionate turn-around time for their decision. Plus they would have chalked up the turn-around time in their performance stats.
The "justification provided regarding purpose and conditions of your trip are not considered reliable" is a grave refusal ground and normally needs a lot of work from the applicant to overcome. If you spend more time on correcting it, they will consider the application more carefully and give a more acceptable turn-around time.
