You're right. What he said in the interview now sounds like a lame excuse to me. He should have vetoed the bill and told the legislature to rewrite the food and drink clause so that it states what he is telling journalists on TV. The clause seems to be defining food and drink as some sort of bribe. Voters who wait in line simply want to have a drink of water or a snack because they're thirsty or hungry after waiting for hours.
I think what the governor was saying in the interview was that this law does not apply to a friend or family member giving someone a bottle of water. However, he did specifically mention BLM. The law's reference to food and drink is ridiculous.
The simple way to avoid all this nonsense and ridiculous laws is to have enough polling places to avoid long lines and to have a national standard on mail-in voting, which has been done for years in states like Colorado without any problems with fraud.
