Yes - it's normally done by pikey builders to save a quid in mortar.

The only time I did it was when adding 1.5 bricks to an opening I was
moving sideways - I removed every half brick from the old edge to get a
keyed joint. Then I put the new bricks in that were over an old brick
upside down so there would be a mortar plug locking the two together -
but I prepacked the new brick's frog first.

My semi-detached is built with upside down bricks, the result is a
lighter wall due to all the empty frogs that is more transparent to
sound from the neighbours than you'd expect.

"Lay London Bricks frog down for maximum strength and weight: when
neither is required, as in most low-rise dwellings, bricks may be laid
frog down."

Erme - that first "down" should be an "upwards"!

Bricks are much quicker to lay frog down, and use much less cement
(depending on size of frog.)
London brickes are pretty ****ty, very weak due to the large frog.

"Normal" bricks, doesn't make a lot of differerce.
Most bricks nowadays are extruded and don't have a frog.
