Ranged effect on basic touch and 360 degree sense

[Russell]

Basic touch is defined as having 360 degree, but the ranged advantage states it gives range in only a 120 degree radius. Does this mean in order to get 360 degree ranged touch sense i need to buy the 360 degree advantage again? Seems kinda unfair to have to buy 360 for a sense that already has it...

As noted on 6E2 9, Normal Touch has Increased Arc Of Perception (360 Degrees), but does not provide that Sense Modifier to other Senses assigned to the Touch Group. By extension of that logic, if a character buys a Sense Modifier (such as Ranged) for Normal Touch and wants that Sense Modifier to function with Increased Arc Of Perception (360 Degrees), he must buy Increased Arc Of Perception (360 Degrees) separately for that ability.
