We currently open WiredTiger transactions in a lazy manner. As batchSize:0 reads do not need to access collection data, we do not start a WiredTiger transaction until the subsequent getMore.
For readConcern level snapshot reads this is counter-intuitive and allows for reading of writes that occur in-between the find and getMore.
