The following Ministry of Foreign Affairs page appears to distinguish between airside transit at a restricted country airport and entering the restricted country:

For the time being, foreign nationals who have stayed in any of the following 152 countries/regions within 14 days prior to the application for landing are denied to enter Japan in pursuant to the Article 5, paragraph (1), item (xiv) of Immigration Control and Refugee Recognition Act, unless special exceptional circumstances are found. Note that foreigners (from the countries and regions where the entry bans do not apply) are not denied to enter Japan even when they arrive in Japan via those countries or regions, which are subject to denial of permission to entry, for refueling or transit purpose. Those who entered those countries or regions will, however, be subject to the entry ban.
I leave it to you to determine whether this has any implications for the case that you described. My interpretation is ... the information does not explicitly state that transit at DXB is exempt from hotel quarantine, but there seems to be a chance that this is the intent.
I am not a lawyer and this is not advice.
