This is why the current thread context in the user-mode debugger after a break-in operation will be in this special thread, which isn't a thread you'll recognize as "yours" if you're

The debugger program keeps track of the initial instructions for each code breakpoint so that it can substitute them in place of the debug break instruction when the breakpoints are hit,
Each SEH exception, whether triggered in hardware or software, is identified in Windows using an integer identifier--the exception code--that indicates the type of fault that triggered the exception (divide-by-zero, access violation, This is a single-byte buffer (as indicated by the value of the fourth argument, nSize, from the previous listing), representing the int 3 instruction.

Hardware exceptions are particularly important to the functionality of user-mode debuggers in Windows because they're also used to implement breakpoints and in single-stepping the target, two fundamental features of any debugger.
