The pattern writer does mention using 2 circs at the beginning of the pattern, although obviously one could use DPNs as you did or ML.
And, echoing the previous posters, you can just give a little extra tug on that first st to tighten it up - I usually tug the second one, too. If you do find that you're forming ladders at some point, you can always rearrange your st so you have 2 knits together, although as Jan says the looseness for most is going between a knit and a purl.
