This is not correct.
If a team is already short-handed, the earliest minor penalty that its players are currently serving will be waived.
In the case of a goal being scored, the penalty with 11 seconds will be cancelled, and the penalty that was delayed will be served in full.
The only exception is that, if the existing penalty is a major or match penalty, it remains on the board, and the delayed penalty will be waived instead (because it would be the only, and therefore the earliest, minor penalty).
See IIHF Rulebook, Rule 114 Delayed Penalty Call - Puck Control & Goals, parts viii and ix for the exact wording that gives rise to this.
