This is because the first partition includes sector 204800 so the
closest that can be allocated to the new partition is the next sector.
This behavior has been changed upstream already by the following commit,
which was released in parted 3.1, and so should be in debian, so I'm not
sure why you are seeing it:

parted: mkpart: DWIM for IEC ending sector numbers like 2MiB and 9GiB
Before, if the user specified start and end in mkpart command using
IEC units, parted created a partition that starts and ends exactly on
these positions. With such behavior, it is impossible to create
partitions as follows: 1MiB-2MiB, 2MiB-3MiB - parted would complain
that it cannot create the second partition, because the first one
occupied sectors 2048-4096 and the second one sectors 4096-3072,
so they would overlap at sector 4096.
With this patch, if the user uses IEC units to specify end of the
partition, parted creates the partition which ends one sector before
the specified position.
