Schumann's Kleine Studie on the Hohner Pianet Demonstration Record

A couple months ago, I realized that Schumann's Kleine Studie from the Album für die Jugend bears some resemblance to the C major prelude in Bach's Well-Tempered Clavier.  As Pieter-Jan Belder briefly mentions in this video for All of Bach, the C major prelude is "like a lesson in harmony."  I think Schumann's Kleine Studie has a similar character, and - like the C major prelude - it's also composed primarily of arpeggios.

Recently, I realized that the recording on the Hohner Pianet Demonstration Record emphasizes this similarity.

In my physical copy of the Album für die Jugend (from the Neil A. Kjos Music Company) and in the notation I downloaded from IMSLP, there are directions to play the piece while using the pedal:

Because the Pianet has no sustain pedal, the piece can't be played this way on it.

It sounds to me that in the demonstration record, the lowest note of these arpeggios is held longer in order to give something of the same effect that using a pedal would.  The first four measures from above are played more like:

Holding that lowest note makes the Kleine Studie more similar to the C major prelude:
