The Gemara answered that Rabbi Elai bar Berekhya referred to studying by rote, by reviewing material one has already learned, which is permitted and even appropriate while traveling, while Rabbi Elazar referred to examining a law in depth, which would likely lead to conflict among scholars. Alternatively, a Baraita read the words of to mean that Joseph told his brothers not to take long strides and should enter a city to spend the night before the sun has set.
