No, that's the mythology that develops around the travels of an apostle Thomas much later on.
I'm pretty sure that there was no 'Thomas.' My guess is that the philosophy of being in a twin universe and a twin of an original humanity ends up anthropomorphized by or before "doubting Thomas" in John and ends up credited with the tradition making those philosophical claims which was also denying the physical resurrection.
In the Gospel of Thomas itself, there's only two mentions of a 'Thomas,' both likely later additions. Moreso the work features him having female disciples and discussions directly with them, and the only later tradition following it claimed a female teacher named Mary as the starting point of their sect.
The Gospel of Thomas is a collection of sayings, and that core may have gone by different names before the 2nd century when it's rolled up in a more secretive context as attributed to 'Thomas' (despite the core itself seemingly being more anti-secretive than any other texts in the early Christian tradition).
