JTO the phrase same but different applies. IIRC the Typhoon Flight Jacket (LSJ/LP) uses Kevlar reinforced Arm Restraint Extension Lines attached to the jacket sleeves (these plug into the seat QRB - QRF in old money), unlike Tornado, where the arm restraint lugs are attached to the jacket arm and the restraint lines were part of the seat (?).
I'd like to say that what happened to you friend wouldn't happen today, from experience the kit is tested to the nth degree via high speed wind-blast testing, live ejections, 'wet drills', burn tests, etc.
