No that does not look like pineappling, See attached picture.
Pineappling is generally multiple distorted stalks coming from the same
spot on the rhizome. Pineappling is thought to be similar to Witches
Broom in other plants. In irises it is thought to be causes by damage
to the growth point often because of a late freeze.

Witches broom on Jack pine is commonly caused by Dwarf Mistletoe – a
tiny flowering, almost inconspicuous parasitic plant. The mistletoe
produces a tiny seed that is propelled great distances onto the growth
of surrounding pine trees. There, the seed germinates, infects the new
tree and begins the cycle again.
In the nursery trade, the densely compact growth habit is often
considered attractive. So desirable is this appearance that several
types of plants infected with witches broom have been selected,
propagated and released as ornamental cultivars. Many “dwarf” cultivars
are examples of witches broom. Below Willow Witches Broom

be an interesting novelty iris depending on what it does.
