Why leaver penalty if you reconnect and win?

Why do you still get leaver penalty if you reconnect and win? Last night blizzard servers disconnected me twice in games i won with friends after i reconnected but still gave me the penalty.

I found a post : Overwatch Technical Issues, SR Loss, and Leaver Penalties

that suggested " reconnect as fast as possible" to help your team win but since reconnection is 1. outside my control, 2. going to give me a loss anyway if i disconnect due to server side issues.

For every disconnect you are given a penalty that is inflected onto your account. Regardless of you re-connecting.

I advise if you still have connection problems, to stop playing competitive and contact Blizzard Technical team or #technical-support.
