Can a pipe have multiple pipe types assigned?

[Anonymous]

In the code, I change the pipe type for two pipes:

pipe.ChangeTypeId(newPipeType.Id);

After commiting the transaction, I change to the Revit UI (see Attachement). 

• When I select each pipe, the new pipe type is shown in the properties >> correct
• When I right click the new pipe type and select Select all Instances | In Entire Project, both pipes get selected >> correct
• When I right click the previous pipe type and select Select all Instances | In Entire Project, no pipes get selected >> correct
• When I delete the new pipe type, both pipes get deleted>> correct
• (after undoing the last step) When I delete the previous pipe type, one pipe gets deleted (!)>> wrong

Allthough I know that it's not possible, it seams that a pipe has assigned two pipe types, the new one and still the previous one.
