removing tefillin after krias hatorah

Is anyone familiar with the custom of removing tefillin after krias hatorah on 1st day chol moed pesach? If so, what's the mekor for that?

No makor, but R' Teitz of Elizabeth, NJ and his family hold this way, due to the fact that the kriah for the first day of chaul hamauŋed bechu"l includes Kadesh Li and V'hoyo ki Y'viecho
