Once the flower stalk touches down at the bottom, the stalk seems to
continue to grow horizontally, putting out plants as it goes. However, it
will produce flowers if it "accidentally" goes out of the water (for
example, if it gets wrapped around the bulbs.) :-)

I suspect this may be the case. Morphology is extremely dependent on
environmental condition. I have found that my Veronica and Horemanii can
easily double in size when given ample macro nutrients(compared to
otherwise healthy nutrient deprived cousins). They seem to have an
insatiable appetite and great ability to store excess in their leaves and
probably in the rootstock. They suck up water column macros so fast that it
can cometimes be hard to grow them in community with small stem plants or
ephiphytes like Bolbitus, unless the water is fed frequently or maintained
with relatively high N & P. BTW, such community cultures are good potential
applications of plant tabs or substrate fertilization (provided that you
like large swords :)). I have never tried limiting CO2, but feel that is
not a good strategy because it might encourage algae.
Here are some old pictures of my bonzai versions.

(30cm) in that picture. My current Veronica which is in the same 125g tank
which gets twice weekly dosing of N&P its leaves are are twice as wide and
up to the surface. I have not noticed a relationship between higher N, P
and more frequent flower stalks
