No.Does that make sense?
there is only 1 grantor and 1 grantee. Subsequent owners of the land are not grantors or grantees.
See the bolded part? That means (specifically the "assigns" term), all subsequent purchasers of the land are "assigns" and are bound by that easement grant."THIS CONVEYANCE IS SUBJECT TO, AND GRANTOR HEREBY RESERVES FOR HIMSELF, HIS HEIRS AND ASSIGNS, A 15-FOOT EASEMENT FOR INGRESS AND EGRESS ACROSS LOT ##, AS SHOWN ON THE ABOVE-REFERENCE PLAT."
