I do not believe they are genetically the same strain and that they are technically variants of one another due to mutation. That said, they should behave relatively the same.
@LumberZach there’s a lot to haze stability but the big cause for clearing is molecular weight of compounds, if they are large and heavy they drop out. The size of the protein chains (malted oats small, flaked oats large), how effective the yeast strain is at binding polyphenols and proteins during fermentation. If you are dip hoping, adding hops from kettle, or dryhoping during fermentation, more binding will occur making longer chains and greater molecular weight which will result in more clearing.
So you would really have to go through your process to see what caused it. I wouldnt suspect it’s solely the yeast strain, probably a combination of factors
