DEXSeq output - untitled columns

Hi everyone.
I’m new to using DEXSeq on Galaxy and had question regarding format of the results file which has 14 labelled columns plus columns for each sample. As I understand it, when initiating an analysis, the primary factor 1 should be the experimental intervention (e.g. treatment) and the second factor 2 should be the reference (e.g. control). In the results table, I am assuming the exon usage coefficients 1 and 2 correspond accordingly to these two variables. But with the untitled columns for the samples, what is the order in which they are arranged? Do the factor 1 sample columns come first before the factor 2 sample columns? I have uploaded a screenshot. Any advice/help would be most appreciated.
