脉 originally meant a blood vessel or pulse — so 一脉 is 'one bloodline/pulse'. Ideas flowing through an unbroken vein from ancestor to descendant.
usage
Mostly neutral or positive — stressing continuity and heritage. Common in art history, philosophy, political rhetoric. Contrast with 如出一辙 which can be negative ('cut from the same cloth').
