[My sentences]
a. He has learnt a lot since he has been here.
b. He has learnt a lot since he was here (=He has learnt a lot since he left here).
(a) and (b) have opposite meanings. However, if we do backshifts of them, then:
c. He had learnt a lot since he had been here.
d. He had learnt a lot since he had been here.
They look the same. So how could we know what they really mean? I mean, (c) and (d) could mean either (a) or (b). And (a) and (b) are opposite .
(Edit: Fixed a typo)
