I prefer that the number of each dummy corresponds with the observation:

Aren't you assuming that the workfile/sample actually starts with the
"right" obs here?

No. Actually, no. This means assuming the first period as the reference
but it is only a convention.
I like this way of generating the seasonal dummies because when I make a
function valid for any seasonality it applies consistent names to the
dummies, and not different names depending on the value of $pd.

That's right, but I prefer that the dummy with "_1" in its name actually
refers to the first quarter/month, not some other convention.
