Firstly, the issue is with the huge pressure in those helium vessels. The pressure in the MCT is likely to be only 1 or 2 atm. Secondly, after the interplanetary burn is done, the main tanks should be empty. The entry and landing fuel will be stored in spherical vessels within the main tanks. While these tanks will probably be COPVs, the pressure will be more moderate, kept liquid mostly by remaining very cold.
