Q: Your article seems to suggest that a T10 ticket can be shared amongst more than one user. Have I understood this correctly? Or does each user need his own T10?
A: This is correct, you can indeed share a T10 ticket (up to a maximum of 10 people). The only condition is that you travel all to the same destination. Note that each person would count as one journey on the ticket e.g. if there was 10 people in your group and they all used the same T10 ticket the ticket would completely used up on the first journey. It is important to note that the T10 ticket is one of the few Barcelona transport tickets that allow multi-person usage so take care if you buy a different type of transport ticket to check the terms and conditions before use.
