Of course!
I don’t suppose Morrisons are stupid, makes sense to recruit well in time for the busy period, by the time the 13 weeks are up the numpties will have revealed themselves and get the boot, but you could bet your last penny if they find any genuine lorry drivers in this recruitment drive they’ll be taken on permanently.
Probationary periods are quite normal on proper jobs, and all jobs will extend the probationary period if there’s a reason where they consider the employee deserves another chance.
The shift patterns i’ve heard about would rule me out from applying, but you would struggle to find an easier, or more boring, job, in lorry world, the minor quibble about 15 minutes of break time unpaid 
means diddly, i’ve only ever been paid straight through on one hourly paid job (favorite job of all, interesting involving some graft and well paid), these days i would expect straight through pay to be on the low hourly rate side, a bit of smoke and mirrors to tempt the unthinking.
