Deeper planting bulbs

In a recent UK TV programme it was implied that planting bulbs deeper
than "normal" discouraged bulbs from increasing by side bulblets, and
consequently gave larger flowers and continuing flowering in subsequent
years. In this case large flowered tulip hybrids were the example. The
commentary I think said "deeper planting, equals cooler bulbs, larger
flowers, longer bulb life", though presumably less bulb increase.
Is this "cooler bulbs point" a valid argument for bulbs like tulips, or
indeed bulbs in general? E.g. some reticulate irises which split up much
more readily than tulips in my experience.
