It does depend on the time of day, as Kaz said.
Most services northwards from Yeovil Pen Mill go, via Westbury, to Bristol Temple Meads. Most GWR services from the South Coast to Worcester and Great Malvern, which you need to change into, also go via Westbury and Bristol Temple Meads. But some Worcester and Great Malvern services start from Temple Meads itself (rather than back at Brighton or Southampton), so that's why you're then told to change at Temple Meads. All depends on what service you're departing Yeovil ....
