Our roof has a peculiar first row of shingles. In most places the first row extended beyond the L-Shaped metal holder by about 5/8". But in some other places it is almost flush with the metal piece. (And in these places we noticed deterioration of fascia boards.)

If this is an error, what is a corrective step?

On the roofs I've done, the shingles (or metal, in one case) extended 1/2" to 1" past the flashing. It does not sound like this is the source of the problem for you. The flashing should protect the fascia from a full water flow, if it is the correct flashing. You describe it as L shaped, but it should have a kick out at the bottom ("drip edge"). I found a decent picture here.

In addition to a small overhang and proper flashing, the final defense for your fascia is a coat of paint. If the fascia is not rotten, you should restore its surface, and prime and paint.

So much flashing used these days is the L-shaped stuff. I personally think this style is far superior because it supports the shingle overhang beyond the fascia board and still has the drip edge.
