Notwithstanding the severance by conveyance, surrender, or otherwise of the reversionary estate in any land comprised in a lease, and notwithstanding the avoidance or cesser in any other manner of the term granted by a lease as to part only of the land comprised therein, every condition or right of re-entry, and every other condition contained in the lease, shall be apportioned, and shall remain annexed to the severed parts of the reversionary estate as severed, and shall be in force with respect to the term whereon each severed part is reversionary, or the term in the part of the land as to which the term has not been surrendered, or has not been avoided or has not otherwise ceased, in like manner as if the land comprised in each severed part, or the land as to which the term remains subsisting, as the case may be, had alone originally been comprised in the lease.
This section applies to leases made before or after the commencement of this Act and whether the severance of the reversionary estate or the partial avoidance or cesser of the term was effected before or after such commencement:
