Because Intel copied the 64 bit instruction extensions developed by AMD so the 
amd64 port of FreeBSD will run on a suitable Intel CPU, eg..

CPU: Intel(R) Pentium(R) 4 CPU 3.00GHz (3000.12-MHz K8-class CPU)
  Origin = "GenuineIntel"  Id = 0xf49  Stepping = 9
  
Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>
  Features2=0x641d<SSE3,RSVD2,MON,DS_CPL,CNTX-ID,CX16,XTPR>
  AMD Features=0x20100800<SYSCALL,NX,LM>

Running in full 64 bit is considerably less kludgy and tends to expose less 
driver bugs than PAE :)
