Wouldn't this be a blend of a few lager yeasts and a few ale yeasts separate from each other ie pure lager or pure ale, not ale & lager mixed ?

My guess is that the lager yeast will produce high levels of maleic acid which gives the beer a strong flavour of green apples.  How strong is hard to say, it depends on how active the yeasts are relative to each other.  I fermented a lager on my balcony in mid december and had to bring it in when the temp dropped to -9C and let it ferment the last sugar indoors.
Indoors fermentation began at 1.018 with a FG of 1.010.
If my memory serves me right OG for the batch was somewhere around 1.040-45.  The final product tasted somewhat like a blend of apple cider and lager beer.
It took some 200g/l of raspberries to mask the apple taste and even then it was noted through the raspberry taste.
