3550's have interface-specific ASICs (which are needed to speed things up)
so you need to associate an interface to "borrow" those.
3560's and 3750's have a different architecture where the ASICs are
chassis-based and therefore not needed to be specifically allocated.

WHY DO 3550s require reflector ports and 3750s don't?
Before you bombard me, I know that 3550s do require reflector port and 3750s
don't ... That's what Cisco told us, but what is the technical
reason????????
Many Thanks
Yemi Salau

3550s definitely do need the reflector ports
