@jinwig i think he meant that if digoxin is given to a normokalemic patient, then they run the risk of developing HYPERkalemia as a result of the K+ buildup extracellularly.
However, you are also correct in saying that hypokalemia is a contraindication to digoxin because of the risk of supratherapeutic levels but I don't think he commented on that.

Mum had heart failure she was suffering from a murmur. She had irregular heart beat. She was given a dose digoxin in morning (Staff Nurse asked me to give it to her in hospital) and another does (maximum 2) two hours later (Staff Nurse again asked me to give it to her in hospital, doctor ordered it, she said, they had just come on their rounds) and about two hours later she was dead. Yet in the morning she was bright and cheerful. She died of congestion leading to cardiac arrest, 4 month ago.

I think he made a slight mistake here, Dig toxicity is seen in hypokalemia, i always remember they are opposite. subtherapeutic in hyperkalemia and supratherapeutic in hyopkalemia. It make sense since if you think of the mechainism, if Dig is competing with K then with less K, you will have more Dig.

I think he was saying that it would cause hyperkalemia, idk.
i was surprised too, because i know that low potassium causes dig toxicity (i guess Digoxin competes with potassium for the Na/K pump)???
